AHK-Cu (Copper Tripeptide-3) 99% High Purity Cosmetic Raw Material Multiple Specifications: 20 mg / 50 mg per vial

What Is AHK-Cu?
AHK-Cu, also known as Copper Tripeptide-3, is a synthetic copper-binding tripeptide composed of the amino acids alanine, histidine, and lysine. It belongs to the family of copper peptides, which are small protein fragments with a high affinity for copper ions. The copper ion is essential for the peptide‘s biological activity, enabling its role in enzymatic processes such as collagen and elastin synthesis, fibroblast activity modulation, and extracellular matrix remodeling.

In research, AHK-Cu has demonstrated significant hair growth-promoting effects. Studies have shown that AHK-Cu at ultra-low concentrations (10⁻¹²–10⁻⁹ M) stimulates the elongation of human hair follicles ex vivo, an effect mediated by increasing the proliferation of dermal papilla cells (DPCs)—the key cellular drivers of hair follicle cycling and growth—while simultaneously preventing their apoptosis. Beyond its hair applications, AHK-Cu has been studied for its anti-aging effects on skin, including enhancing extracellular matrix (ECM) components, increasing the expression of Elastin and COL3A1 genes to improve skin elasticity and firmness, providing photoaging defense by suppressing MMP-1 induced by UVA radiation to protect collagen and skin structure, and promoting cellular regeneration and skin vitality.

Our AHK-Cu is supplied as a high-purity (≥99%) blue lyophilized powder, available in 20 mg and 50 mg vials, with CAS 682809-81-0.

Why Choose Our AHK-Cu with Multiple Specifications?
Pick the right amount for your formulation needs. The 20 mg vial is perfect for small-batch DIY formulations, test runs, or pilot studies. The 50 mg vial suits larger production batches or extended research protocols. The 50 mg size offers better value per milligram for commercial formulators.

Science-backed hair growth efficacy. AHK-Cu is not just another copper peptide. It has been validated in peer-reviewed research for its ability to stimulate human hair follicle elongation by enhancing dermal papilla cell proliferation while preventing apoptosis. This dual mechanism makes it exceptionally effective for hair growth formulations.

Dual hair and skincare versatility. AHK-Cu uniquely bridges the haircare and skincare markets. It can be incorporated into hair growth serums, scalp treatments, anti-hair loss shampoos, anti-aging creams, eye serums, and post-procedure skin repair formulations. This versatility maximizes its value for formulators.

Enhanced stability and targeted activity. Compared to GHK-Cu, AHK-Cu (with alanine replacing glycine) exhibits potentially enhanced stability and more targeted biological activity, particularly for hair follicle applications. This structural advantage makes it the preferred choice for specialized hair growth formulas.

Gentle and well-tolerated. When used as directed in external formulations at recommended concentrations (0.05%–0.5%), AHK-Cu is generally non-irritating and suitable for sensitive skin and scalps.

Same high purity across both sizes. Whether you order 20 mg or 50 mg, you receive the same ≥99% purity, same COA traceability, and same rigorous quality standards.

Ready to ship. Vacuum-sealed, discreet packaging with cold chain options available. Every batch includes COA documentation. Contact us to request a quote for your preferred vial size and quantity.
