Analyst Comments
Blue lyophilized powder, black-cap vial, received sealed. GHK-Cu and KPV were measured on a second HPLC-UV method; both chromatograms are shown. TB-500 was detected in fragment form (Ac-LKKTETQ, the short 7 amino acid piece of thymosin beta-4 often sold as TB-500), not as full-length TB4. It is reported as detected but not quantified: the amount is small and a fragment reference standard is being added, after which the mg can be reported. Updated November 10, 2026.
