The supplier confirms the final price and availability when you order. 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.

Peptide Biosciences: testing and transparency
Peptide Biosciences is a United Kingdom-based research-peptide supplier listing 16 of the peptides we track, priced in GBP. Where it does well: states its products are independently tested; links a certificates-of-analysis page (not yet reviewed by us). Where it falls short: prices 25% above the market median per mg; we found no contact details beyond the website. Our Transparency Score is 4.3/10, provisional until more of our criteria have been assessed.
