How we review. We compare each product on the vendor’s own page on the date shown: price, vial size, price per mg, stated purity and whether a batch-specific COA from a third-party lab is published. We do not run lab tests ourselves and we do not test peptides on people. Rankings are updated when prices or COAs change. Last checked: November 2026.
