AHK-Cu
AHK-Cu (Copper Tripeptide-3, Alanine-Histidine-Lysine Copper) is a copper peptide similar to GHK-Cu but with different properties. It's used for hair growth and skin rejuvenation applications.
Mechanism of Action
The copper-binding tripeptide stimulates collagen synthesis and may promote hair follicle enlargement. Works similarly to GHK-Cu but may have distinct receptor interactions.

Typical Dosage (Research)
Topical: 0.5-2% concentration in serums for skin or scalp applications. Often combined with other growth factors for hair formulations.
Topical application to skin or scalp. Can be used with microneedling for enhanced penetration. May cause temporary blue-green tint at high concentrations.
Considerations for Men & Women
Women: Copper tripeptide primarily used topically for hair growth and skin rejuvenation. No sex-specific differences in topical application. May benefit female pattern hair thinning when applied to the scalp.
Men: May benefit male pattern hair loss when used topically alongside other treatments. Same skin rejuvenation properties. No sex-specific dose adjustments for topical use.
