GHK-Cu vs AHK-Cu
GHK-Cu and AHK-Cu are copper-binding peptide complexes studied in skin- and matrix-research models. Here is a factual comparison and a per-milligram price check across vendors.
GHK-Cu is a copper-binding tripeptide complex (glycyl-L-histidyl-L-lysine + copper) studied in skin and extracellular-matrix research models.
AHK-Cu is a copper-binding tripeptide complex (alanyl-L-histidyl-L-lysine + copper) studied in keratinocyte and hair-follicle research models.

- First residue: GHK-Cu begins with glycine; AHK-Cu begins with alanine.
- Research context: GHK-Cu is the more widely studied copper peptide; AHK-Cu is studied more in follicle-research models.
- Both are supplied as copper-complexed peptides and are commonly available in larger (50–100 mg) vials.
