Tiers name what a vendor publishes, not a verdict on any product's purity or quality. Lab-verifiable COAs: certificates that open on the testing lab's own site (the seal's ring shows what share of them do). Third-party COAs: certificates attributed to a third-party lab, which may be hosted only on the vendor's site. Tiers follow the Vendor Score (90+ and 80–89), which is 87% COA evidence; the numeral in each seal is that score. Affiliate relationships never affect tiers, selection or order. How the Vendor Score works
A thymic peptide preparation studied in research contexts for immune-regulation pathways.

Multi-peptide products (e.g. BPC-157 + TB-500). We don't rank these by $/mgPrice divided by the milligrams of active compound — the like-for-like way to compare cost across different vial sizes. — a per-milligram figure across different peptides isn't comparable — so they're listed separately by total price and kept out of the headline index above.
Thymalin is described in the literature as a polypeptide complex extracted from thymus tissue and studied as an immunomodulator, chiefly in cultured cells and animals plus older, uncontrolled human clinical reports.
