AHK-Cu (Copper AHK) Dosing & Reconstitution Guide

AHK-Cu is the copper-complexed form of the AHK tripeptide. The addition of copper enhances its biological activity, particularly in stimulating dermal papilla cells for hair growth and wound healing applications. Used in topical cosmetic formulations.

Mechanism: Copper-dependent enzyme activation enhances dermal papilla cell stimulation. The copper complex promotes angiogenesis and ECM remodeling, with enhanced bioactivity compared to the non-copper form.

Route: Topical

Frequency: 1–2 times daily

Dose Range: Serums containing AHK-Cu complex (typically 50–500 ppm)

Superior hair growth stimulation vs AHK alone In vitro data shows enhanced dermal papilla cell proliferation compared to AHK alone (Pyo HK et al., J Dermatol Sci, 2021).

The safety profile of AHK-Cu has been assessed in various studies, indicating that while it is generally well-tolerated, there is a potential for skin irritation, particularly at higher concentrations. Individuals with known copper sensitivity should exercise caution, as hypersensitivity reactions may occur. It is essential for researchers to consider these factors when designing studies or utilizing AHK-Cu in formulations. The presence of copper in the complex may also lead to adverse effects in sensitive populations, highlighting the importance of thorough preclinical evaluations to ensure appropriate usage.
