GHK-Cu + AHK-Cu Blend — 100mg Vial | Copper Peptide - VPeptide GHK-Cu + AHK-Cu Blend

Description

GHK-Cu + AHK-Cu Dual Copper Peptide Blend combines the two most extensively-characterized copper-binding tripeptides in a single lyophilized sterile research vial — 50 milligrams of GHK-Cu (Glycyl-L-Histidyl-L-Lysine copper(II) complex) plus 50 milligrams of AHK-Cu (Alanyl-L-Histidyl-L-Lysine copper(II) complex) for 100mg total dual copper peptide content per vial. GHK-Cu and AHK-Cu are structurally related copper tripeptides differing only by a single N-terminal residue substitution (glycine → alanine), making them ideal comparative research compounds for copper peptide SAR studies. GHK-Cu (identified by Loren Pickart in 1973 in human plasma) has been extensively investigated for wound repair chemistry, dermal remodeling research, and connective tissue research applications, while AHK-Cu is associated in cosmetic chemistry literature with hair follicle and dermal papilla research. Both peptides coordinate to divalent copper (Cu²⁺) through the histidine imidazole and N-terminal amine, forming stable peptide-copper complexes with characteristic deep blue color. This 100mg dual-peptide lyophilized presentation is offered for laboratory research applications investigating combined copper peptide research, comparative GHK-Cu vs AHK-Cu SAR studies, copper coordination chemistry research, and copper tripeptide combined research applications.

Benefits (Research Focus)

• Combined copper peptide research — studied as a dual copper peptide combined lyophilized research format bringing both GHK-Cu and AHK-Cu into single sterile reconstitution

• Comparative copper peptide SAR — investigated for direct comparative research between GHK-Cu (glycine N-terminus) and AHK-Cu (alanine N-terminus) copper tripeptides

• Copper coordination chemistry — explored for Cu²⁺ binding properties and peptide-metal complex stability across two structurally-related copper tripeptides

• Skin + hair copper peptide research — examined for combined GHK-Cu (skin-focused research literature) + AHK-Cu (hair-focused research literature) research applications

• Sterile injectable research format — researched in sterile lyophilized combined vial format for research applications requiring sterile reconstitution
