Buying GHK-Cu in the UK
GHK-Cu is glycyl-L-histidyl-L-lysine, a copper-binding tripeptide supplied as the copper(II) complex, lyophilised for laboratory research. This guide covers buying it in the UK — and because we sell it in two sizes, mostly the arithmetic of choosing between them. The evidence and regulatory status live in the library entry.
50mg or 100mg — the arithmetic
The 50mg vial is £21.99 and the 100mg vial is £39.99 — £0.44 and £0.40 per milligram respectively. The 100mg is the better price per milligram and one of very few 100mg presentations sold in the UK at all; the 50mg is the smaller commitment. Both count toward the multibuy bands, which apply by themselves from three vials. GHK-Cu is also a component of the Glow Set, which includes the diluent.
