Identity

What AHK-Cu is

AHK-Cu is short for a tiny three-link chain of amino acids, alanine, histidine, and lysine, wrapped around a copper ion the way a small claw holds a marble. It belongs to the same general family as GHK-Cu, a much better known copper tripeptide, but swaps one amino acid link and pairs it with a different overall sequence. Copper is the reason peptide-copper complexes like this one are often described as blue or blue-green in solution.

AHK-Cu is a laboratory reference material. SBz Industries sells it for laboratory research.

Available sizes: 50 mg, 100 mg

Research

What the research has looked at

In plain terms, with a link to every study. The most useful thing to notice is what each study was done in.

Independent, verifiable research specific to AHK-Cu is very thin. A PubMed search under its formal name and synonyms turns up essentially one study that actually used AHK-Cu; other results that surface under similar search terms turn out to involve related but different copper-binding peptides, such as DAHK or AHH.

cells2007

Researchers took small pieces of donated human scalp tissue, isolated individual hair follicles, and grew them in dishes alongside separately cultured hair-follicle support cells called dermal papilla cells. Adding AHK-Cu increased how much the follicles elongated and how well the support cells survived and divided, compared to follicles and cells that didn't receive it.

Handling

Mixing and storage

Full handling guide

01
Let it warm up
Give the vial twenty minutes on the bench before opening it, so water does not condense onto the powder.
02
Add bacteriostatic water
Slowly, down the inside wall of the vial, never straight onto the powder.
03
Let it dissolve
Leave it alone until it clears. Do not shake it. Shaking damages the peptide.
04
Refrigerate and use
Once mixed, it breaks down much faster than the dry powder. Keep it cold and dark.

Documentation

Tested before it goes on sale

An independent lab tests every compound we sell. It confirms the compound is what the label says and measures purity by HPLC.

The latest certificate is on the product page, so you can read the result before you order.

Questions

Common questions about AHK-Cu

What is AHK-Cu?

AHK-Cu is short for a tiny three-link chain of amino acids, alanine, histidine, and lysine, wrapped around a copper ion the way a small claw holds a marble. It belongs to the same general family as GHK-Cu, a much better known copper tripeptide, but swaps one amino acid link and pairs it with a different overall sequence. Copper is the reason peptide-copper complexes like this one are often described as blue or blue-green in solution. SBz Industries sells it for laboratory research only.

Is AHK-Cu the same as GHK-Cu?

No. Both are copper-binding tripeptides sharing a histidine-lysine backbone, but GHK-Cu starts with glycine while AHK-Cu starts with alanine. They're structurally similar cousins, not the same molecule, and most well-known copper-peptide research is actually on GHK-Cu.

Has AHK-Cu been tested in people?

No published human study turned up. The one identifiable study used donated human skin tissue and cells grown in a lab, not a living volunteer.

How is AHK-Cu reconstituted?

AHK-Cu ships as a freeze-dried powder. Mix it with bacteriostatic water, added slowly down the inside wall of the vial, and let it dissolve without shaking. The researcher decides the working concentration, not us, and we publish no protocols.

How should AHK-Cu be stored?

Store as stated on the product page and the certificate of analysis. Vials ship in plain outer packaging with no product name on the outside.

Is AHK-Cu tested, and can I see the results?

Yes. An independent lab tests every compound: it confirms the compound is what the label says and measures purity by HPLC. The latest certificate is on the product page, and you can read it before you order.

Who is permitted to purchase AHK-Cu?

Researchers and institutions, 21 or over. By ordering you confirm the material is for laboratory research and will not be used in humans or animals.
