How these numbers are made
Every night The Peptide Index reads vendors’ public catalog pages, records the listed price and stated peptide content, and divides one by the other to get a comparable $/mg. Blends and topical/cosmetic products are excluded from single-compound figures. Read how $/mg works, the about page and how vendor signals are checked.
