For Research Use OnlyGHK-Cu (Copper Peptide)
GHK-Cu is a three-residue peptide coordinated to a copper ion, and the complex rather than the peptide alone is the functional species. Supplied lyophilised at 50mg for $45 or 100mg for $75, which is $0.90 and $0.75 per mg respectively. Confirm copper content on the certificate: a document establishing only the peptide portion has verified half the molecule, and the half it omits is arguably the more important. Copper is catalytic in oxidative chemistry, meaning it is not consumed by the reactions it drives, so store this apart from anything that depends on staying reduced. Research use only.
