AHK-Cu Peptide

$180.00

AHK-Cu is a synthetic copper peptide designed to resemble GHK-Cu, but it has a much higher affinity to hair follicles. This water-based serum is made for people who want a minimalist ingredient list in their hair serum for daily care.

AHK-Cu Peptides are used in research settings to understand: 

  • Fast-Absorbing, Water-Light Texture: Equipped with a fine-mist spray, this serum is distributed evenly without the feeling of heaviness, making it comfortable on the scalp, whether wet or dry, and layering effortlessly with the rest of your routine. 
  • Clean, Minimal Ingredients: Made without fragrance, dyes, or heavy additives so that the focus remains on the star ingredient: AHK-Cu to target hair follicle health. 
  • Peptide Quality You Can Trust: All our formulations are made with shelf-stable peptides and tested for purity.

ahk-cu molecular structure

What is AHK-Cu

AHK-Cu is a copper tripeptide, a small amino acid chain bound to copper. It’s closely related to GHK-Cu — one of the most recognized copper peptides in cosmetic products. AHK-Cu is different in that it’s entirely laboratory-made, modelled after the naturally occurring GHK-Cu peptide. 

It’s becoming a popular ingredient in hair and scalp treatments because of its affinity for hair follicles. It’s also easy to work with in many water-based formulations, as it’s lightweight and feels comfortable on the skin.

AHK-Cu Chemical Information

Sequence:  Ala–His–Lys chelated to Cu²⁺
Molecular formula: C₁₄H₂₄CICuN₆O₄
Molecular weight: ~ 451.39 g/mol
Form: Synthetic peptide, spray
Other Ingredients: AHK-Cu, Lab-Grade Distilled Water

The AHK-Cu Hair Serum is manufactured with high-purity material and undergoes in-house and independent lab analysis to confirm:

  • Identify (peptide sequencing verification)
  • Purity (≥99% by HPLC)
  • Absence of contaminants (microbial, heavy metals, solvents)

Lab testing ensures that the tablets are consistent, high-quality, and suitable for research purposes.

Research Related to AHK-Cu

The following sections outline what scientists have studied about AHK-Cu. This information is for context only and shouldn’t be taken to mean that our AHK-Cu hair serum will produce the same results.

Lab Studies on Hair Follicle Health

Researchers examined how human hair follicles behave in a lab dish when exposed to AHK-Cu-type copper peptide. 

They found that hair strands grew longer in culture, remained in the anagen growth phase for longer, and that key cells in the follicle were more active, showing fewer signs of cell death [1].

Scalp Health & Aging

Reviews on copper peptides and hair aging suggest that AHK-Cu may help the scalp environment by supporting the structures around hair follicles, reducing oxidative stress, and calming low-level irritation linked to hair loss and aging hair [2].
