Best suppliers that accept crypto

A long-running supplier that takes cards, ships internationally and knows how to publish a proper lot-numbered certificate, then stopped doing so in 2023.

Some of the most traceable batch certificates in this group, from a company that will not tell you its address, phone number or name.

A UK SARMs-first shop with budget peptide prices, a real street address and phone, card payment and a 14-day money-back window.

A capsule-heavy research-chemical store with one of the larger public lab-results pages in this group and a purity refund you could actually claim, carrying an FDA warning letter from December 2024 and a returns policy that excludes peptides and adds fees.

Open certificates from two named laboratories and free US shipping with no minimum, on a mixed SARMs-and-peptides catalog that carries a 2021 FDA warning letter, files its certificates by date rather than lot, and has no returns policy at all.

A budget-tier Chinese direct supplier with crypto-only checkout, a Janoshik verification route and a long file of Finnrick-documented warnings, from lookalike domains to a forum ban for doxxing a customer.

Extreme Peptides has traded since 2010, answers a phone, takes card, Bitcoin and ACH and ships free from $99.

American Research Pens describes a thorough testing program and had not published a single lot certificate when we checked, while charging about twice what a comparable pen supplier does.

Enhanced Peptides is easy to order from, with free shipping on every US order and three ways to pay, and impossible to audit, because its 99%+ HPLC claim comes with no certificate, no laboratory and no report.

A mixed research-chemical retailer with an FDA warning letter from September 2025, a middling independent testing record reported by Finnrick, and a website we could not load to confirm a single claim.

The main Atomik Labz site refused to load for us, and the sister storefront that did load shows prices, a crypto discount and not a single certificate, laboratory name or address.
