Product names, photos, quantities and prices are as publicly listed by the supplier; photos load from the supplier’s own website. “vs market” compares price per mg with the median across tracked suppliers listing the same peptide in the same currency; prices are never converted between currencies. We do not sell these products and give no guidance on their use.

Testing & transparency
For readers who want the detail: what Xeno says about testing, the certificates of analysis we hold, and our transparency score. This is separate from the PepFinder rating above.
Transparency review · updated 23 Sept 2026
Xeno: testing and transparency
Xeno is a United States-based research-peptide supplier listing 13 of the peptides we track, priced in USD. Where it does well: states independent testing and names Chromate and Freedom Diagnostics; links a certificates-of-analysis page. Where it falls short: only zelle, venmo, cash app and cryptocurrency shown: no card payments with chargeback protection; a new website: online for less than a year. Our editorial score is 6.0/10, provisional until more of our criteria have been assessed.
