GHK-Cu vs BPC-157
GHK-Cu and BPC-157 differ in size and composition. GHK-Cu is a copper(II) complex of the tripeptide Gly-His-Lys (C14H22CuN6O4, ~401.9 g/mol). BPC-157 is a linear 15-residue peptide, GEPPPGKPADDAGLV (C62H98N16O22, 1419.56 g/mol), with no bound metal. Both are supplied as lyophilized powder.

Часто задаваемые вопросы
Why does GHK-Cu list two CAS numbers?+
CAS 89030-95-5 identifies the copper(II) complex that is supplied; CAS 49557-75-7 identifies the free GHK tripeptide without copper. BPC-157 has a single CAS number, 137525-51-0.
How do their molecular weights compare?+
BPC-157 is the larger molecule at 1419.56 g/mol (15 residues) versus ~401.9 g/mol for GHK-Cu (3 residues plus copper). BPC-157 is commonly supplied as the acetate salt, so the exact species and net peptide content of a lot are reported on its Certificate of Analysis.
Are GHK-Cu and BPC-157 available in the same vial?+
Yes. Both are components of the GHK-Cu / BPC-157 / TB-500 Blend (GLOW, 70 mg total) and the GHK-Cu / KPV / BPC-157 / TB-500 Blend (KLOW, 80 mg total), each a single-vial lyophilized research blend.
