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 short peptide bioregulator studied in early research contexts around immune/thymic tissue.
Evidence brief
Thymogen is described in the literature as a synthetic dipeptide, L-Glu-L-Trp, developed from an immunomodulatory molecule isolated from the thymus preparation Thymalin and studied as an immunostimulant.
