About the compound

AHK-Cu substitutes alanine for the glycine of GHK-Cu, producing a copper-binding tripeptide with a distinct research profile. It is most often encountered in studies of dermal papilla cells and follicle organ cultures.

Supplied as a lyophilized powder. Researchers pairing AHK-Cu with GHK-Cu frequently order both to compare copper-peptide activity across assays.
