Description
About AHK-Cu
AHK-Cu is copper tripeptide-3 — Ala-His-Lys complexed with copper(II). It is closely related to GHK-Cu (Gly-His-Lys copper complex, tripeptide-1): both are short copper-chelating peptides with the histidine residue serving as the primary Cu(II) binding site, and both are studied in connective-tissue and skin biology. The sequences differ, and so do the research profiles — GHK-Cu has an extensive cross-tissue literature, while AHK-Cu research has focused more specifically on hair follicle biology and dermal papilla cell function.
Mechanism of Action
Dermal papilla cells are specialized fibroblasts at the base of each hair follicle that regulate cycling and growth. In published follicle models, AHK-Cu stimulates dermal papilla cell proliferation and extends hair follicle elongation ex vivo. The signalling shifts two growth factors in opposite directions: VEGF is upregulated (supporting follicular vascularity) while TGF-beta1 is downregulated — both consistent with anagen-phase maintenance in the cited in vitro models.
Published Research
- Human hair growth in vitro: a tripeptide-copper complex (AHK-Cu) at 10-12–10-9 M stimulated elongation of human hair follicles and proliferation of cultured dermal papilla cells in vitro (“The effect of tripeptide-copper complex on human hair growth in vitro”).
- Growth-factor modulation: in cited dermal-fibroblast models, AHK-Cu elevated vascular endothelial growth factor (VEGF) production while decreasing transforming growth factor-beta1 (TGF-beta1) secretion.
- Transdermal delivery: skin-penetration studies have characterized copper-tripeptide distribution across skin layers, relevant to researchers designing topical delivery systems.

Why researchers choose CertaPeptides
Who actually tests this?
Selected lots are independently verified by Janoshik Analytical (Czech Republic) and published on the Janoshik public portal. Other lots ship with the supplier's batch specification. See /coa for the published wall.
View COAs →What if I get the wrong batch?
Every vial label carries a code. Look it up on our Verify page: it shows what CertaPeptides publishes for that code and, for a withdrawn lot, that the lot was withdrawn and why. If yours is withdrawn, or if the code on your label finds nothing, email us that code.
View COAs →Where does it ship from?
Romania (EU). We are CERTALAB SRL, CUI 54169956, VAT-registered. Sameday for Romania, GLS for most EU destinations, TCE Worldwide for the remaining cross-border EU and non-EU markets (UK, Switzerland). Delivery 1–15 business days depending on destination — exact window shown at checkout.
Shipping details →What if there's a problem?
You have a 14-day withdrawal right under OUG 34/2014 (Romanian/EU consumer law), with escalation to ANPC and alternative dispute resolution (SAL) available. Contact us at support@chinapeptideshop.com.
Returns policy →Product Information
This product is intended for scientific research and development purposes only. It is a chemical substance that shall not be used as a drug, medicine, active substance, or ingredient in any product intended for human or animal consumption. Researchers must handle this compound in accordance with their institutional biosafety guidelines. Use only in properly equipped laboratory settings with appropriate personal protective equipment.
Peptides in lyophilized (freeze-dried) form are shipped in sealed glass vials using standard delivery methods and do not require refrigeration during transit. Lyophilized peptides are highly stable at ambient temperatures for the duration of standard shipping (typical transit windows are shown at checkout). Once received, transfer the product to refrigerated storage (2–8°C) promptly.
Frequently Asked
Research peptides are supplied in lyophilized (freeze-dried) form. The amount of material is typically only a few milligrams — appearing as a very thin film or small pellet at the bottom of the vial, often nearly invisible. This is completely normal.
Unlike some suppliers who add bulk fillers (such as Mannitol), CertaPeptides provides pure peptide without unnecessary additives.
