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.
Disclaimer. For information and research purposes only. Not medical or legal advice. Selank and semax are not a licensed medicine in the UK and not approved by the FDA for human use. Most vendors listed are US-based and price in US dollars - confirm UK delivery and import rules before ordering; Reviva X ships from UK stock and prices in pounds. Some links are affiliate links; they do not change our rankings.
