Can I sell this on Stripe, Shopify or PayPal?

None of the three name peptides at all, which is exactly the problem. Merchants read that silence as permission, build the store, and find out where they stand only when a review freezes the balance. The absence of the word means the decision was deferred to an underwriter, not that it was made in your favour.

This is the one category of the fourteen where a mainstream processor says yes in writing, and the yes is narrower than most merchants read it as. Stripe permits CBD on stated conditions about THC content. Everything sold on the strength of being intoxicating sits outside that permission, whatever the label says.

Supplements are the one category here where the governing clause is explicit, and it does not turn on what you sell. Stripe prohibits nutraceuticals that are unsafe or that make harmful claims, so an ordinary vitamin brand passes and the same brand with disease language on the product page does not.

Weight loss carries every risk on this page simultaneously: an outcome claim in the product name, an unusually high dispute rate, and in the GLP-1 era a supply chain that runs into prescription-drug territory. Stripe names one weight-loss product specifically, and everything else is judged on claims.

Not one of the three names kratom anywhere. It is also banned outright in several US states and unscheduled federally, which means the payments question and the legality question have different answers depending on where the parcel goes. Processors resolve that ambiguity by declining.

Unnamed by all three, and the closest thing to a named clause is PayPal's, which puts steroids in the same breath as narcotics. SARMs sit in the worst available position: not explicitly banned, so merchants believe they are fine, and close enough to an explicitly banned category that no reviewer will spend long on the distinction.

The most survivable category on this list, and the one where merchants most often lose an account they could have kept. Nootropics are unnamed everywhere, and a catalogue of caffeine, L-theanine and B-vitamins is genuinely low risk. Add one unapproved-drug compound and the whole account inherits that compound's risk profile.

This is the only category on the page where Stripe's prohibition hangs on a single word, and the word is not "research". Stripe prohibits incorrectly labelled research chemicals. A genuine laboratory supplier with accurate labelling is in a materially different position from a consumer store using the term as cover.

Stripe names telemedicine and restricts rather than prohibits it, so compliant telehealth is genuinely bankable. The line that decides your outcome is prescription fulfilment. A consultation platform and a business that ships the drug afterwards are different underwriting propositions wearing the same website.

Stripe names e-cigarettes and permits them under a lawfulness condition. PayPal names cigarettes flatly. The bigger operational problem for most vape merchants is not the processor at all: it is that age verification and shipping law are conditions of the permission, and failing them retroactively voids it.

Stripe permits firearms in limited circumstances. PayPal prohibits them along with parts and accessories. The trap here is accessories: merchants who sell no firearms at all routinely assume they are outside the category and find that the policies reach parts and components too.

Stripe restricts exchanges and wallets with limited availability. The critical distinction, and the one merchants ask about most, is that accepting crypto as payment for an ordinary product is not what these clauses cover. Being the exchange is the regulated activity; taking payment in it is not.

Prohibited by Stripe by name, including credit monitoring and counselling, and covered by PayPal's financial services clause. A service business with no product risk at all is treated more severely here than several of the ingestible categories above, because the risk being priced is the dispute rate and the regulatory attention, not the safety of anything.

The least ambiguous category here. Stripe prohibits it outright and the prohibition explicitly extends to text and imagery, not just video. PayPal restricts sexually oriented material. There is no reading of either policy that gets a mainstream processor to yes.
