Research peptide suppliers get shut down by Stripe, Shopify Payments, and PayPal every week. We place RUO businesses with acquiring banks that actually underwrite the category — and we review your site before you apply, so you get approved and stay approved.
Tell us about your business — we'll review your site and get back to you within one business day.
Research peptides sit in one of the most scrutinized corners of payments right now. The FDA has been sending warning letters to online peptide sellers — including a Texas-based seller in August 2026 — stating that “research use only” labels don’t hold up when the rest of the site points to human use.
The card networks have followed. Banks that board peptide merchants selling prescription-drug compounds have been hit with brand assessments, so acquirers now underwrite RUO carefully — and mainstream processors avoid it entirely.
That doesn’t mean you can’t take cards. It means your site, your catalog, and your account have to be set up right from the start.
Online stores selling research peptides to labs, institutions, and qualified researchers with compliant labeling and third-party testing.

Reagents, lab equipment, and research consumables shops that carry peptides as part of a broader catalog.
