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.

Transparency review · updated 24 Sept 2026
Opti-Gen Peptides: testing and transparency
Opti-Gen Peptides is a United Kingdom-based research-peptide supplier listing 18 of the peptides we track, priced in GBP.

Where it falls short: we found no statement of independent testing on its website. Our Transparency Score is 4.8/10, provisional until more of our criteria have been assessed.
