About this tool

PepAssess is an independent directory for comparing research peptide vendors. Each vendor profile brings together its Evidence Score, lab reports checked against the issuing lab's public records, prices, payment options and coupon codes. Peptide comparison pages show prices per mg and which vendors have lab-confirmed reports. The site also includes a map of U.S. peptide vendors and a reconstitution calculator for lab use. PepAssess helps visitors compare the evidence vendors publish before choos
