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

Featured stores

Placed here by PeptidesGrid, not ranked by lab score; the table below is.

All vendors

Score: Finnrick's "Purity focus" score, the share of tests Finnrick could classify that pass at 99.5%+ purity with a measured amount of peptide within 35% of the label, pulled toward the middle when there are few tests. No score means no tests Finnrick could classify yet, which says nothing either way. vs median: the vendor's typical price against the market. Each listing's $/mg is divided by that peptide's median $/mg, and the column shows the middle of those figures (under 1.00x is cheaper). It needs 3 or more listings; likely listing errors are left out. A dot means none or not stated. US? (or any other place followed by a question mark): Finnrick gives the location with a question mark, and the store's pages do not confirm it.
