Research peptide vendors by Finnrick lab score, with prices and shipping

All vendors

Score: Finnrick's "Purity focus" score, the share of classifiable tests passing at 99.5%+ purity with a dose within 35% of the label, pulled toward the middle when there are few tests. No score means no classifiable tests yet, which says nothing either way. vs median: the vendor's typical $/mg divided by the market median (under 1.00x is cheaper), from 3 or more listings.
