How we rank peptide vendors
We rank vendors before we monetize them. This page documents exactly how.
Vendor scores are based on transparent quality signals, not commission rates. Some vendors we rank have affiliate programs with us; others do not. Affiliate status is disclosed on every vendor profile. Our top-ranked vendor may not be an affiliate.
