About GHK-Cu
GHK-Cu is a copper-bound tripeptide (Gly-His-Lys) with a distinctive deep-blue reconstituted colour. It is one of the most-referenced copper peptides in skin, hair and connective-tissue research literature.
Why the 100mg vial
The 100mg format is the highest-value size for extended research protocols — enough compound per vial to run structured studies without repeat reconstitution.
Purity and testing
Every batch is HPLC and mass-spec verified at 99%+ purity, sealed and batch-numbered, and matched to a Certificate of Analysis available on the COA page.
