What is AHK-Cu?

AHK-Cu pairs a short three-amino-acid backbone with a bound copper ion, coordinated mainly through the histidine imidazole ring. This copper-peptide architecture places it in the same broad family as the better-known GHK-Cu, though the two are distinct molecules with different sequences and reported activity profiles.

This listing is AHK-Cu (10 vials × 100mg) from TFC Peptides (Tianjin, China), sold on Stairway to Gray with escrow: your payment is held until the order arrives and only then released to the brand.

How it is understood to work

The bound copper ion gives the complex redox activity, allowing it to participate in electron-transfer reactions relevant to oxidative signaling. In cell and tissue models, AHK-Cu has been associated with upregulation of collagen and elastin gene expression and with cues that influence dermal fibroblast and hair-follicle cell behavior.

Research status

Research on AHK-Cu spans in vitro fibroblast assays, skin-equivalent models, and early work on hair-follicle activity, alongside broader interest in wound-healing and anti-inflammatory pathways. Evidence is concentrated at the cell-culture and animal-model stage; there are no approved drug products built on this exact peptide.

Lab testing

There is no public lab report for this listing yet. We can ask the brand for the batch COA before you order. Many buyers also split an independent HPLC test with others who bought the same batch.

Bought through escrow: the brand is only paid after you confirm delivery. If the parcel never arrives, or an independent test shows the wrong compound or a significant under-fill, open a claim before releasing payment.

Specifications

Compound: AHK-Cu
Also known as: Copper Tripeptide-3, Alanyl-Histidyl-Lysine-Copper
Class: Copper-binding tripeptide complex
Form: Raw powder (bulk, not in vials)
Molecular formula: C₁₅H₂₄ClCuN₆O₄
Molecular weight: 451.39 g/mol
Sequence: Ala-His-Lys-Cu
Per vial: 100mg
Units per kit: 10
Brand: TFC Peptides · Tianjin, China

Handling & storage

Supplied as a raw powder rather than a pre-filled vial kit; copper-peptide complexes are characteristically blue in solution, and the dry powder should be kept sealed, cool, and away from moisture to prevent premature complex degradation.

Concentration check: adding 2 ml of bacteriostatic water to one 100mg vial gives 50 mg/ml. The Research Lab calculator in your dashboard works this out for any volume.

Questions

How is AHK-Cu different from GHK-Cu?

Both are copper-binding tripeptides used in skin research, but they have different amino-acid sequences (Ala-His-Lys vs Gly-His-Lys) and are studied as distinct molecules with their own, only partially overlapping, activity data.

Why is this sold as a raw powder rather than a vial kit?

Raw powder format is intended for external or formulation-based laboratory work rather than reconstitution into an injectable-style research solution, so it is packaged and priced differently from the lyophilized single-peptide vials.

How much AHK-Cu is in this kit?

10 vials of 100mg each. The lab testing section above shows what the brand’s tested sample actually contained, where a report exists.
