Does PayPal Allow Peptides? PayPal and Braintree Rules

Neither PayPal nor Braintree names peptides, and neither says it accepts research peptide sales. PayPal's acceptable use policy puts prescription items in the row the page numbers 8 in its pre-approval chart, and Braintree's policy lists "pseudo pharmaceuticals" among the business categories its services may not be used for, as both pages read on October 8, 2026.

This guide is for founders and operators of research use only (RUO) peptide stores. It reads both acceptable use policies line by line, puts them side by side, shows how FDA read past a research use only label in two August 2026 warning letters, and turns it all into checks to run before you apply. Every quotation is copied from its source. Where the sources say nothing, this guide says so.

Does PayPal allow peptides?

PayPal does not name peptides. Its acceptable use policy puts prescription items behind pre-approval: the row the page numbers 8 in its pre-approval chart is "Prescription Items," described as "The sale of any product(s) requiring a prescription or prescription dispensing services." The chart is introduced with "PayPal requires pre-approval to accept payments for certain services as detailed in the chart below," and the same chart lists "Medical Items or Services" and "Telemedicine Services." Source: PayPal Acceptable Use Policy.

The captured page says nothing about research peptide sellers or research chemicals. What it does address is a set of activities and categories a peptide store can fall into, depending on how it labels, describes, bundles and sells its products. The sections below walk through each one.

What does PayPal's Acceptable Use Policy actually contain?

The captured United States page has an opening paragraph, a "Prohibited Activities" section, an "Activities Requiring Approval" section, a short "More Information" section and a section on violations. A prohibited activity is something you may not use PayPal for at all. An activity requiring approval needs PayPal's pre-approval first. Source: PayPal Acceptable Use Policy.

The opening paragraph

The page opens with "You are independently responsible for complying with all applicable laws in all of your actions related to your use of PayPal's services, regardless of the purpose of the use." It then says "Violation of this Acceptable Use Policy constitutes a violation of the PayPal User Agreement." Source: PayPal Acceptable Use Policy.

In our reading, this first sentence matters most to a peptide store. A research use only label states a purpose, and the opening says your legal duties apply whatever the purpose. The User Agreement itself is not in the evidence this guide draws on, so what follows from a breach of it is not covered here.

The five prohibited activity items

The "Prohibited Activities" section opens with "You may not use the PayPal service for activities that:" and lists five items. The page prints no numbers on them; the numbering below is our count, used to refer back to them. Source: PayPal Acceptable Use Policy.

1. "violate any law, statute, ordinance or regulation."

2. By our count of the page's lettered list, transactions involving eleven product types, from "(a) narcotics, steroids, certain controlled substances or other products that present a risk to consumer safety" through "(k) certain weapons or knives regulated under applicable law."

3. By our count of the page's lettered list, transactions of nine kinds, from "(a) show the personal information of third parties in violation of applicable law" through "(i) involve offering or receiving payments for the purpose of bribery or corruption."

4. Activities that "involve the sales of products or services identified by government agencies to have a high likelihood of being fraudulent."

5. Activities that "relate to transactions involving any activity that requires pre-approval without having obtained said approval."

Item 5 is the link between the two lists. If a store falls in a pre-approval row and has not obtained the approval, the store is also inside a prohibited activity. Source: PayPal Acceptable Use Policy.

The pre-approval chart

The chart quoted above prints a Section column numbered 1 through 18, each row with a category and a description, and its description column carries the words "not intended to be an exhaustive list." Source: PayPal Acceptable Use Policy.

So no row naming your product does not put you outside pre-approval. Read the rows as examples.

Which PayPal prohibited activities can a research peptide store touch?

This section delivers outcome 1 of 5: find the PayPal lines that reach your store.

These are the items whose wording can reach a store that sells research peptides online. Each check line is our recommendation, not PayPal's.

"violate any law, statute, ordinance or regulation"

This is item 1, the broadest line on the page. If a regulator reads your store as selling something the law restricts, this is where that reading lands on your PayPal account. Source: PayPal Acceptable Use Policy.

What to check: whether any page could be read the way FDA read the two stores covered below.

"other products that present a risk to consumer safety"

Item 2 covers transactions involving "(a) narcotics, steroids, certain controlled substances or other products that present a risk to consumer safety." The page does not define the last phrase. Source: PayPal Acceptable Use Policy.

What to check: who decides what presents that risk. In our reading, agency statements are the likely reference point, and in both August 2026 letters FDA wrote that "injectable drug products can pose risks of serious harm to users." Sources: FDA warning letter to NuScience Peptides LLC, FDA warning letter to Peptide Partners LLC.

"(b) drug paraphernalia"

Item 2 also lists "(b) drug paraphernalia." The page does not define the term. Source: PayPal Acceptable Use Policy.

What to check: accessories you sell next to peptides. The published sources do not say which accessories PayPal treats as paraphernalia. They do show FDA citing what a store sold alongside its peptides, covered below.

"(d) items that encourage, promote, facilitate or instruct others to engage in illegal activity"

This is also in item 2. What to check: guides, calculators, blog posts and support replies that read as instructions for use. This line can reach that content even when the product page is clean. Source: PayPal Acceptable Use Policy.

"(d) are for the sale of certain items before the seller has control or possession of the item"

This is in item 3, and the page does not say which items "certain" covers. What to check: preorders, presales and group buys paid before stock is in your hands. See our guide to peptide preorders and shipping delays. Source: PayPal Acceptable Use Policy.

"(b) support pyramid or ponzi schemes, matrix programs, other 'get rich quick' schemes or certain multi-level marketing programs"

This is also in item 3. What to check: affiliate and rep programs that pay for recruiting other sellers, not only for sales. Source: PayPal Acceptable Use Policy.

"(e) are by payment processors to collect payments on behalf of merchants"

This is item 3 again. What to check: whether your account ever takes money for another business's sales, such as a white label or drop ship partner who asks you to take their payments. Source: PayPal Acceptable Use Policy.

"involve the sales of products or services identified by government agencies to have a high likelihood of being fraudulent"

This is item 4. The page names no agency or list, and the sources behind this guide show no agency naming research peptides as likely fraudulent. Watch agency notices with the FDA warning letter tracker. Source: PayPal Acceptable Use Policy.

Which PayPal pre-approval rows can a research peptide store touch?

This section delivers outcome 2 of 5: pick your pre-approval rows.

Of the chart's rows (the page numbers them up to 18), these are the ones whose wording can reach a peptide store's catalog, marketing or checkout. Source: PayPal Acceptable Use Policy.

Row 8: Prescription Items

"The sale of any product(s) requiring a prescription or prescription dispensing services." The row does not say who decides whether a product requires a prescription. Source: PayPal Acceptable Use Policy.

What to check: whether any product name matches an approved prescription drug, or any page links to material about one. FDA cited such names in August 2026, covered below.

Row 9: Telemedicine Services

"Providing medical services and consultations in a remote fashion." Source: PayPal Acceptable Use Policy.

What to check: any consult, coaching or chat offer on your site or a partner's site you link to.

Row 16: Medical Items or Services

"All items classified as medical devices, and all services or treatment provided by a person or organization holding itself out as a provider of health-care services," with licensed health care services and "Medical Tourism" named inside it. Source: PayPal Acceptable Use Policy.

What to check: equipment that could be classed as a medical device, and any page that presents your business as a health care provider. "Holding itself out" is about how you present yourself, not your license.

Row 17: Multilevel Marketing and Direct Selling Organizations

The row describes models "in which products or services are sold via a network of independent distributors or representatives." It adds that "DSO and MLM models rely on personal sales and frequently require the independent distributors to recruit new distributors in order to advance within the organization or gain incentive compensation." Source: PayPal Acceptable Use Policy.

What to check: rep programs and tiered payouts that reward recruiting.

Row 18: Marketplaces

"A marketplace is an e-commerce solution where third-party sellers can sell their products or services to customers." Source: PayPal Acceptable Use Policy.

What to check: whether other vendors list products on your site.

Row 6: Gambling, Gaming, Prize Draws and Contests

The row covers "any other activity with an entry fee and a prize," and names "sweepstakes" among its examples. Source: PayPal Acceptable Use Policy.

What to check: giveaways that need a purchase to enter. In our reading, a purchase used as an entry fee is close to this row's wording.

Row 4: Payment Facilitator

The row says its services "would also include the sale of stored value cards and escrow services." Source: PayPal Acceptable Use Policy.

What to check: gift cards and store credit you sell for cash.

What does pre-approval mean in PayPal's own words?

The policy uses the word without defining a process. Here is everything the captured page says about it. Source: PayPal Acceptable Use Policy.

• The section's first line, quoted at the top of this guide, speaks of "certain services." The chart's header row reads "PayPal requires pre-approval to accept payments for certain items and services as detailed below," adding the word "items."
• The description column is headed "Item or Service Requiring Pre-Approval" and marked "not intended to be an exhaustive list."
• The contact column reads "If you have questions about obtaining a pre-approval or opening a new PayPal Business account that offers services requiring pre-approval, please contact our" Sales team, with a link.
• The violations section reads "If you have a question about whether a type of transaction may violate the Acceptable Use Policy, or wish to file a report, you can do so" through a link.

Four things follow from the wording, read plainly. First, pre-approval comes before payments, not after. Second, it covers items as well as services. Third, the route to it is a conversation with PayPal's Sales team, not a form named on the page. Fourth, the page does not publish criteria, documents, timelines or fees for approval. Source: PayPal Acceptable Use Policy.

A practical way to handle this: if you think a row reaches your store, put the question to PayPal in writing before you take a single payment, describe your products in plain words, and keep the reply. Under item 5, taking payments in such a category "without having obtained said approval" is itself prohibited. Source: PayPal Acceptable Use Policy.

Does Braintree allow peptides?

Braintree does not name peptides either. Its section "2. Certain Business Categories" opens with "You may not use the Payment Services in connection with any product, service, transaction or activity that involves," and the list that follows includes "pseudo pharmaceuticals," "prescription drugs, illegal drugs or substances designed to mimic illegal drugs," and "online or other non-face-to-face pharmacies or pharmacy referral services." Source: Braintree Acceptable Use Policy.

What does Braintree's Acceptable Use Policy actually contain?

This section delivers outcome 3 of 5: read Braintree's policy section by section.

Braintree's page opens by naming itself "Braintree, a division of PayPal, Inc." and saying that by using its "Payment Services" you agree to comply with the policy. It has four sections, which the page numbers: "1. Restricted Activities," "2. Certain Business Categories," "3. Actions by Braintree," and "4. Amendments." The captured page shows "Last updated on November 8, 2017." Source: Braintree Acceptable Use Policy.

Unlike PayPal's page, Braintree's has no pre-approval chart. Its business category list is a list of what the services may not be used for, with "prior written approval" exceptions written into only a few items: airlines, gambling, membership subscriptions longer than a year, personal computer technical support, tour operators, and travel agencies or travel clubs. None of the pharmaceutical items carries that exception. Source: Braintree Acceptable Use Policy.

The amendments section reads "This Acceptable Use Policy may be amended by Braintree at any time by posting a new version of it to our website." Read the live page before you apply. Source: Braintree Acceptable Use Policy.

Section 1: the six restricted activities

Section 1 opens with "You may not use the Payment Services in connection with any product, service, transaction or activity that involves:" and, by our count, lists six items. Each can reach a peptide store. Source: Braintree Acceptable Use Policy.

• "Violates any law or government regulation, or promotes or facilitates such by third parties." The last part reaches content that helps a customer break the law.
• "Violates any rule or regulation of Visa, Mastercard, American Express, Discover, JCB, Diners Club card, China UnionPay or any other electronic funds transfer network (each, a 'Card Network')." Card network rules are not in this guide's evidence.
• "Is fraudulent, deceptive, unfair or predatory."
• "Causes or threatens reputational damage to us or any Card Network."
• "Involves any of the business categories listed in Section 2."
• "Results in or creates a significant risk of chargebacks, penalties, damages or other harm or liability." This reaches your dispute rate. Source: Braintree Acceptable Use Policy.

Section 2: the business categories a peptide store can touch

By our count, Section 2 lists more than fifty categories. These are the ones whose wording can reach a research peptide store. Source: Braintree Acceptable Use Policy.

• "pseudo pharmaceuticals." The term is not defined on the page. In our reading, it is the closest line on either policy to a product sold with drug-like descriptions under a non-drug label.
• "prescription drugs, illegal drugs or substances designed to mimic illegal drugs." On the may not list, not a pre-approval chart.
• "online or other non-face-to-face pharmacies or pharmacy referral services." This reaches referral links too.
• "drug paraphernalia." Same words as PayPal's item 2(b).
• "age restricted products or services." The page does not say which products count.
• "multi-level marketing or pyramid schemes."
• "offering substantial rebates or special incentives to the cardholder subsequent to the original purchase." This reaches aggressive loyalty and cashback programs.
• "membership subscriptions > 1 year (exceptions apply if you get our prior written approval)." This reaches long prepaid plans.
• "pre-payment services." In our reading, this sits close to preorders and presales.
• "evading card association chargeback monitoring programs." This reaches splitting volume across accounts.
• "quasi-cash or stored value." This reaches gift cards and prepaid store credit.
• "aggregation or factoring, whether licensed or unlicensed." This reaches taking payments for other sellers.

Section 3: what Braintree can do

Section 3 opens with "If, in our sole discretion, we believe that you may have engaged in any violation of this Acceptable Use Policy, we may (with or without notice to you) take such actions as we deem appropriate to mitigate risk to Braintree and any impacted third parties and to ensure compliance with this Acceptable Use Policy." By our count it then lists six actions, introduced by "Such actions may include, without limitation:" Source: Braintree Acceptable Use Policy.

• "Blocking the settlement or completion of one or more payments."
• "Suspending, restricting or terminating your access to and use of the Payment Services."
• "Terminating our business relationship with you, including termination without liability to Braintree of any payment service agreement between you and Braintree."
• "Taking legal action against you."
• "Contacting and disclosing information related to such violations to (i) persons who have purchased goods or services from you, (ii) any banks or Card Networks involved with your business or transactions, (iii) law enforcement or regulatory agencies, and (iv) other third parties that may have been impacted by such violations."
• "Assessing against you any fees, penalties, assessments or expenses (including reasonable attorneys' fees) that we may incur as a result of such violations, which you agree to pay promptly upon notice."

In our reading, the standard is Braintree's belief that a violation may have happened, judged in its sole discretion, not a finding that it did. Because it may act without notice, the first sign can be a blocked payout, and the disclosure action reaches your customers, banks and regulators. Source: Braintree Acceptable Use Policy.

Where do PayPal and Braintree say the same thing, and where do they differ?

Braintree calls itself a division of PayPal, Inc., but the two policies are separate documents with different structures and different wording. The table sets the lines a peptide store cares about side by side. All wording is quoted from the PayPal Acceptable Use Policy and the Braintree Acceptable Use Policy.

In our reading, the practical difference is this. On PayPal's page, prescription items sit in a chart whose route is a pre-approval conversation. On Braintree's page, prescription drugs and pseudo pharmaceuticals sit in a list with no approval route written into those items. Where they agree is the broad lines: both bar use that breaks the law, both name drug paraphernalia, both reach selling before you hold stock, and both reach multi-level marketing.

How did FDA read past a research use only label in August 2026?

This section delivers outcome 4 of 5: explain how FDA read past the label.

Both policies turn on the law. The clearest recent record of how it is read for research peptide stores is two FDA warning letters dated August 24, 2026, to NuScience Peptides LLC and Peptide Partners LLC. Both were issued by FDA's "Center for Drug Evaluation and Research (CDER)," and both open with "This warning letter advises you of significant violations observed during a U.S. Food and Drug Administration (FDA) review of your website." Sources: FDA warning letter to NuScience Peptides LLC, FDA warning letter to Peptide Partners LLC.

What the labels said

Both stores had research use only wording, and FDA quoted it. To NuScience Peptides LLC, FDA wrote: "Despite statements on your product labeling marketing your products 'for laboratory, research, and analytical use' and 'not intended for human or veterinary use,' evidence obtained from your website establishes that your products are intended to be drugs for human use." Source: FDA warning letter to NuScience Peptides LLC.

To Peptide Partners LLC, FDA wrote: "Despite statements on your product labeling marketing your products 'for research use only' and 'not for human or veterinary use,' evidence obtained from your website establishes that your products are intended to be drugs for human use." Source: FDA warning letter to Peptide Partners LLC.

Both passages sit in footnote 1. The label was there, and the rest of the website outweighed it.

The rule FDA applied

Both letters say the examples they list "provide evidence of the intended use (as defined in 21 CFR 201.128) of these products as drugs." That regulation says intended use refers to "the objective intent of the persons legally responsible for the labeling of an article (or their representatives)," and that "The intent may be shown by such persons' expressions, the design or composition of the article, or by the circumstances surrounding the distribution of the article." It adds: "This objective intent may, for example, be shown by labeling claims, advertising matter, or oral or written statements by such persons or their representatives." Sources: FDA warning letter to NuScience Peptides LLC, 21 CFR 201.128.

That list is wider than a product label. In our reading, product pages, blog posts, emails, social posts, support replies and what you sell together all count. Source: 21 CFR 201.128.

The evidence FDA cited

Reading the two letters side by side, FDA cited five kinds of evidence. This guide does not repeat the product descriptions FDA quoted, because they describe what compounds do in a body.

1. Product names. By our count, the NuScience letter lists nine products and the Peptide Partners letter lists seven, each including a bacteriostatic water or reconstitution solution product, as "unapproved new drugs under section 505(a)." Several of the names include the names of approved drug substances. Sources: FDA warning letter to NuScience Peptides LLC, FDA warning letter to Peptide Partners LLC.

2. Product page text. Each letter quotes passages from named product pages, introduced as "Examples from your product labeling, including on your website." Many read as research summaries, and FDA quoted them as evidence anyway. Source: FDA warning letter to NuScience Peptides LLC.

3. A hyperlinked page. In the NuScience letter, one cited passage came from a page on a public chemistry database, which FDA said was hyperlinked from the store's product page. A link out was read as part of the store's labeling. Source: FDA warning letter to NuScience Peptides LLC.

4. What was sold together. To NuScience: "The sale of these products together demonstrates that you intend for your 'Bacteriostatic water for Peptides (BAC Water)' to be used in combination for injection." To Peptide Partners: "The sale of these products together demonstrates that you intend for your 'Reconstitution Solution (BAC)' to be used in combination for injection." Sources: FDA warning letter to NuScience Peptides LLC, FDA warning letter to Peptide Partners LLC.

5. Tools on the site. The NuScience footnote adds: "In addition to the cited drug claims, you market bacteriostatic water alongside a 'peptide calculator,' a resource that provides the means to prepare an injectable drug for human administration." Source: FDA warning letter to NuScience Peptides LLC.

What FDA concluded and asked for

FDA said the products "are drugs under section 201(g)(1) of the FD&C Act, 21 U.S.C. 321(g)(1), because they are intended for use in the diagnosis, cure, mitigation, treatment, or prevention of disease, and/or intended to affect the structure or any function of the body." It asked for a response "within fifteen (15) business days of receipt of this letter," and warned that "Failure to adequately address violations may result in regulatory or legal action without further notice including, without limitation, seizure and injunction." Source: FDA warning letter to NuScience Peptides LLC.

Why this matters for a PayPal or Braintree application

The published sources do not say how PayPal or Braintree reviewers read a store. In our reading, both policies' law lines send a reviewer to the same place FDA went. If FDA can read your website as selling unapproved drugs, the label does not shield you on either policy, and the same pages are what a payment reviewer sees. Sources: PayPal Acceptable Use Policy, Braintree Acceptable Use Policy.

What should you check on your product pages and checkout copy before you apply?

This section delivers outcome 5 of 5: audit your pages before you apply.

Each check is our recommendation, tied to a policy line or to evidence FDA cited. Run them on the live site, because that is what a reviewer and a regulator read. For the full page structure, see our anatomy of a compliant peptide product page.

Product names

FDA listed product names that include approved drug substance names, and both policies name prescription products. List every product name and flag each that matches or abbreviates an approved drug's name. Decide each with counsel, but know the count before a reviewer does. Sources: FDA warning letter to Peptide Partners LLC, PayPal Acceptable Use Policy, Braintree Acceptable Use Policy.

Product descriptions

FDA quoted research summaries from product pages, framed as research, as evidence of intended use. Read every description and flag any sentence that says or suggests what a compound does in a body, in people or in animals, including summaries of published studies. Our recommendation is to keep descriptions to identity, specification, batch testing and handling. Source: FDA warning letter to NuScience Peptides LLC.

Outbound links

FDA cited a hyperlinked page as part of a store's labeling. List every outbound link on your product pages and blog. For each one, ask whether you would be comfortable having its text quoted as your own claim. Source: FDA warning letter to NuScience Peptides LLC.

Bundles, accessories and tools

FDA cited what was sold together and an on-site calculator, and both policies name drug paraphernalia. Check what you sell together, what your cart suggests as add-ons, and what calculators or dosing style tools you host. Sources: FDA warning letter to NuScience Peptides LLC, PayPal Acceptable Use Policy, Braintree Acceptable Use Policy.

The research use only statement itself

Both stores had one, and it did not decide the outcome. Check that it appears on every product page, the cart and the order confirmation, and that nothing else on the page contradicts it. In our reading, a contradiction is what Braintree's "deceptive" wording reaches. Sources: FDA warning letter to Peptide Partners LLC, Braintree Acceptable Use Policy.

Checkout copy, emails and support replies

21 CFR 201.128 counts "oral or written statements" and "advertising matter." Read your checkout page, order confirmation, shipping and abandoned cart emails and saved support macros with the same eye as the product page, because a support reply is where staff most often answer a use question they should decline. Source: 21 CFR 201.128.

Preorders, subscriptions, rebates and giveaways

Both policies reach selling before you hold stock, PayPal's chart covers prize draws with an entry fee, and Braintree lists long memberships, substantial rebates and pre-payment services, as quoted above. Write down which of these your store runs. Sources: PayPal Acceptable Use Policy, Braintree Acceptable Use Policy.

Affiliates, reps and other sellers

Both policies reach multi-level marketing and taking payments for others, and PayPal's chart adds marketplaces, as quoted above. Write down how affiliates are paid and whether anyone else's products or payments run through your account. Sources: PayPal Acceptable Use Policy, Braintree Acceptable Use Policy.

Disputes and refunds

Braintree names chargeback risk and evading chargeback monitoring, as quoted above. Check that your refund policy, shipping times and order status emails would make sense to a buyer who never reads the terms. Source: Braintree Acceptable Use Policy.

What should you do if your PayPal or Braintree account is limited?

Braintree's six listed actions and PayPal's User Agreement line are quoted above. Neither captured page describes an appeal process, a review timeline, or how long funds may be held. Sources: Braintree Acceptable Use Policy, PayPal Acceptable Use Policy.

A practical way to handle the first days:

1. Read the notice in full and write down the exact reason given, the date, and any documents asked for. Do not reply on impulse.

2. Match the stated reason to the policy line it points to, using the sections above.

3. Freeze changes that make the record look worse, such as editing product pages in a way that hides what was there. Save dated copies of your pages as they stood.

4. Answer only what is asked, describe your products accurately, and keep copies of everything you send.

5. Do not move the same sales to another merchant's account, and do not open new accounts to spread volume. Both moves sit close to lines quoted above on taking payments for others and evading chargeback monitoring.

Stripe publishes a different document with different wording. Its list of prohibited and restricted businesses names "Pseudo-pharmaceuticals or nutraceuticals that are not safe or make harmful claims" and "Incorrectly labeled research chemicals."

Your pre-application checklist

Work through this before you open a PayPal Business account or apply to Braintree. Each line is our recommendation. Keep the answers in one dated document.

1. Re-read the live PayPal Acceptable Use Policy and Braintree Acceptable Use Policy and note anything that changed since October 8, 2026.

2. Write a one paragraph plain description of what you sell, to whom, and how. Use the same words in every application.

3. Flag product names that match approved drug names, description sentences about what a compound does in a body, and outbound links you would not quote as your own.

4. List every accessory, bundle, cart add-on and on-site tool, and decide which you keep.

5. Confirm your research use only statement appears on each product page, the cart and the order confirmation, and that nothing on the same page contradicts it.

6. Read checkout copy, transactional emails, abandoned cart emails and support macros for use language.

7. Write down whether you run preorders, long subscriptions, rebates, purchase-to-enter giveaways, gift cards, store credit or affiliate tiers, and whether any other seller's payments touch your account.

8. Check each item against PayPal's pre-approval rows (numbered up to 18 on the page) and note every row you might fall in.

9. For each such row, put the question to PayPal's Sales team in writing before taking payments, and keep the reply.

10. Note that Braintree's pharmaceutical items carry no written approval route, and decide whether to apply there at all.

11. Check your refund policy, shipping times and dispute history, and write down your current dispute count.

12. Save dated copies of every page as submitted.

13. Have counsel read the FDA section of this guide against your site. See our guide to choosing a peptide business attorney.

For a broader underwriting list that covers other processors, see the peptide merchant account underwriting checklist.

Self check

Answer each question before reading its answer. If you miss one, reread the section named after it.

1. Does PayPal's captured policy page name peptides?

No. PayPal does not name peptides, and the captured page says nothing about research peptide sellers. See Does PayPal allow peptides?.

2. Which row of PayPal's pre-approval chart covers prescription items?

The row the page numbers 8. See Row 8: Prescription Items.

3. What does PayPal's policy say about an activity that needs pre-approval when you have not obtained it?

You may not use the service for it. See What does pre-approval mean in PayPal's own words?.

4. Which two entries on Braintree's list of business categories should a peptide store read first?

Pseudo pharmaceuticals, and prescription drugs, illegal drugs or substances designed to mimic illegal drugs. See Section 2: the business categories a peptide store can touch.

5. Did research use only wording on the labels decide the outcome in FDA's August 2026 letters?

No. FDA found that evidence from each website established the products were intended to be drugs. See How did FDA read past a research use only label in August 2026?.

6. Could you hand over a flagged product name list, an outbound link list and a one paragraph product description today?

If not, finish the checklist before you open an application. See Your pre-application checklist.

Frequently Asked Questions
