A high-purity copper-binding tripeptide for advanced scalp, hair-care and cosmetic peptide formulation.
AHK-Cu is the copper(II) complex of the Ala-His-Lys tripeptide. Unlike the better-known GHK-Cu, AHK-Cu has a different first amino acid, with its most directly relevant study focused on human hair follicles ex vivo and dermal papilla cells in vitro. (See our GHK-Cu vs AHK-Cu comparison to choose the right fit.) [R1–R2] This 99% blue powder is intended for measured R&D and controlled cosmetic formulation. 

  • 99% blue peptide powder for precise bench and pilot formulation.
  • Directly studied in human hair-follicle ex-vivo and dermal-papilla-cell models. [R1–R2]
  • Useful for premium scalp-serum, hair-tonic and copper-peptide development concepts.

Key Benefits

Supports scalp and hair-care innovation — AHK-Cu is useful when a formulation brief calls for a copper peptide with research directly connected to follicle and dermal-papilla biology. 

Relevant to fuller-, healthier-looking hair concepts — In a 2007 laboratory study, AHK-Cu stimulated elongation of isolated human hair follicles ex vivo and increased proliferation of cultured dermal papilla cells. [R1–R2] 

High-purity format for controlled development — The 99% powder format lets formulators prepare measured stock solutions, run compatibility work and evaluate the ingredient across multiple prototype concentrations without being locked into a pre-diluted carrier.

Why Formulators Choose AHK-Cu

AHK-Cu is a focused choice for formulators who want a copper peptide specifically associated with hair-follicle research rather than simply another version of GHK-Cu. The published evidence is directly relevant: Pyo and colleagues evaluated AHK-Cu in isolated human hair follicles and cultured dermal papilla cells, reporting increased follicle elongation and cell proliferation across picomolar-to-nanomolar laboratory exposures. [R1–R2] Those laboratory concentrations are not a finished-cosmetic dosage recommendation, but the study gives AHK-Cu a clear research identity for scalp and hair-care development. (See our GHK-Cu vs AHK-Cu comparison to choose the right fit.) 

Typical Applications

Why Source From Us

  1. Start with samples scale to bulk orders – one supplier from trial to production: Validate with lab samples, then scale to commercial volumes – same quality, same team. No re-qualification, no project delays.
  2. Formulation support that actually helps – not just a data sheet: We give you hands-on guidance on solubility, temperature, pH, and compatibility. A real formulation partner, not a catalog.
  3. Reliable supply chain – consistent quality, on-time delivery, batch after batch: Own manufacturing facilities plus long-term partnerships with audited upstream producers ensure batch-to-batch consistency. Full documentation with every shipment. No "sample passes, bulk fails"
  4. Export-ready documentation – compliance, customs, cleared：Complete technical documentation packages – COA, MSDS, TDS, stability data – batch-specific and regulatory-ready. We handle the paperwork so your compliance and procurement teams can focus on formulation

Frequently Asked Questions

What is AHK-Cu?

AHK-Cu is the copper(II) complex of the tripeptide alanine-histidine-lysine (Ala-His-Lys). It is commonly marketed in the cosmetic ingredient trade as Copper Tripeptide-3.

Is AHK-Cu the same as GHK-Cu?

No. AHK-Cu begins with alanine, while GHK-Cu begins with glycine. They are related copper-binding tripeptides but different ingredients with different evidence bases.

Does AHK-Cu have human clinical evidence for hair growth?

The key published study used isolated human hair follicles ex vivo and cultured dermal papilla cells in vitro. It was not a controlled human topical clinical trial. [R1–R2]

What percentage of AHK-Cu should I use?

A universal independently established cosmetic use level was not identified. Use the current grade's TDS / specification as a starting point and validate the finished formula.

Is AHK-Cu water soluble?

Current commercial suppliers describe high-purity AHK-Cu powder as water-soluble. Confirm the selected grade's solubility instructions before setting the process. [R4–R5]

Can AHK-Cu be combined with acids, vitamin C or chelators?

Potentially, but copper coordination and peptide stability can be affected by strong pH shifts, reducing or oxidizing environments and metal-binding ingredients. Validate the exact system instead of assuming compatibility.

Why is the powder blue?

The blue appearance is characteristic of the copper-containing complex in current commercial AHK-Cu powders. Appearance should still be checked against the current lot specification.

What should I review before bulk purchase?

Review current identity / sequence data, HPLC assay basis, appearance, copper-complex basis and other lot-specific quality fields, together with the documentation required for your destination market.
