AHK-Cu is a synthetic copper-associated tripeptide consisting of three amino acids—alanine, histidine, and lysine—that form a complex with a copper ion. It is commonly identified in research literature as AHK-Cu or Copper Tripeptide-3.
In contrast to GHK-Cu (Copper Tripeptide-1), a naturally occurring copper-binding peptide that has been detected in biological fluids such as plasma, saliva, and urine, AHK-Cu is a synthetically produced peptide developed for experimental research. Its alanine–histidine–lysine sequence has been investigated for its interactions with cellular signaling pathways, particularly those associated with dermal papilla cell activity, hair follicle biology, and cellular survival mechanisms. Preclinical research has explored its potential effects on follicular tissue and related signaling processes, although these findings remain primarily based on laboratory and ex-vivo studies.

The effect of tripeptide-copper complex on human hair growth in vitro
Pyo HK et al. (2007) examined L-alanyl-L-histidyl-L-lysine-Cu²⁺ (AHK-Cu) using cultured dermal papilla cells and isolated human hair follicles.
The researchers reported that AHK-Cu:
• stimulated proliferation of cultured dermal papilla cells;
• promoted elongation of human hair follicles in an ex-vivo model;
• increased the Bcl-2/Bax ratio;
• reduced levels of cleaved caspase-3 and PARP in treated cells;
• was associated with changes consistent with reduced apoptotic signaling.
AHK-Cu should not automatically be assumed to have all of the biological effects reported for GHK-Cu. Although the two compounds are closely related copper tripeptides, AHK-Cu has an alanine residue at the N-terminus whereas GHK-Cu has glycine. The direct evidence base for AHK-Cu is considerably smaller.

Storage Instructions:
All of our products are manufactured using the Lyophilization (Freeze Drying) process, which ensures that our products remain 100% stable for shipping for up to 3-4 months.
Once the peptides are reconstituted (mixed with bacteriostatic water), they must be stored in the fridge to maintain stability. After reconstitution, the peptides will remain stable for up to 30 days.
Lyophilization is a unique dehydration process, also known as cryodesiccation, where the peptides are frozen and then subjected to low pressure. This causes the water in the peptide vial to sublimate directly from solid to gas, leaving behind a stable, crystalline white structure known as lyophilized peptide. The puffy white powder can be stored at room temperature until you’re ready to reconstitute it with bacteriostatic water.
Once peptides have been received, it is imperative that they are kept cold and away from light. If the peptides will be used immediately, or in the next several days, weeks or months, short-term refrigeration under 4C (39F) is generally acceptable. Lyophilized peptides are usually stable at room temperatures for several weeks or more, so if they will be utilized within weeks or months such storage is typically adequate.
However, for longer term storage (several months to years) it is more preferable to store peptides in a freezer at -80C (-112F). When storing peptides for months or even years, freezing is optimal in order to preserve the peptide’s stability.
