AHK-Cu Raw Powder · 1000MG

AHK-Cu (Alanyl-L-Histidyl-L-Lysine copper(II) complex) is a copper-binding tripeptide structurally related to the well-known GHK-Cu peptide, with alanine substituted for glycine at the N-terminus. AHK-Cu is associated with hair follicle and dermal papilla research in the cosmetic chemistry literature and is the active copper peptide featured in many high-end hair density serum formulations. Like GHK-Cu, AHK-Cu coordinates to a divalent copper ion (Cu²⁺) through the histidine imidazole and N-terminal amine, forming a stable peptide-copper complex with a characteristic deep blue color. This 1000mg presentation is supplied as a raw powder bulk material — the standard format for cosmetic formulation development and larger-scale research applications. AHK-Cu has been investigated in cosmetic chemistry literature for hair follicle dermal papilla research, copper coordination chemistry, and comparative SAR studies versus GHK-Cu. This material is supplied as high-purity research-grade raw AHK-Cu powder for laboratory, formulation, and research applications.

• Extended research protocols — supports larger-scale or longer-duration research applications requiring substantial material quantities

• Multi-experiment research — single bulk batch supports multiple research workstreams

• Comparative GHK-Cu vs AHK-Cu SAR research — sufficient material for direct comparative studies between the two copper tripeptides

• Reference standard applications — bulk reference material for analytical method development and validation

Research Focus Areas

• Hair follicle research — dermal papilla cell research and hair density-related cosmetic chemistry endpoints

• Copper coordination chemistry — investigated for Cu²⁺ binding properties and peptide-metal complex stability versus GHK-Cu
