Compare before you buy.
Compare peptide prices across verified suppliers, normalised to cost per mg, with lab-verified COAs and current discount codes.
Fast, accurate, transparent peptide monitoring for the modern researcher. We built PepLookup because comparing peptide pricing across suppliers meant opening a dozen tabs and doing the cost-per-mg math by hand, normalising every listing down to one number lets you see the real comparison in one place.
Real numbers or none at all
Every price on this site carries the time it was last observed. We show empty states rather than a placeholder price, a fabricated review count, or a mocked-up COA.
Ranked by price, not commission
When we do earn a commission from a listed supplier, it never changes the price a buyer pays and never changes where that supplier ranks. That policy is disclosed on every page it applies to.
We are a comparison tool, not a seller
PepLookup does not manufacture, sell, or ship anything. Every purchase happens directly between you and a third-party supplier, see our full disclaimer for the details.
