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.

ExtolX is a United Kingdom-based research-peptide supplier listing 20 of the peptides we track, priced in GBP. Where it does well: states independent testing and names Janoshik; states a company registration number (17314659). Where it falls short: only bank transfer shown: no card payments with chargeback protection; we found no published certificates of analysis. Our Transparency Score is 5.7/10, provisional until more of our criteria have been assessed.
