Important Notice
This product is intended for laboratory and research use only. Not for human or veterinary use. By purchasing, you confirm this product will be used exclusively for in-vitro research purposes.
Reconstitution Required
This peptide ships lyophilized (dry powder) and requires bacteriostatic water to reconstitute before use. BAC water is sold separately.
When This Product May Not Suit Your Research
- ⚠If your research requires GMP-grade material for clinical applications — research-grade peptides are not intended for clinical use.
- ⚠If your lab lacks proper cold storage (-20°C freezer) — this peptide's stability may be compromised at higher temperatures.
- ⚠If your study protocol requires FDA-approved reference standards — contact USP or a certified reference material provider.
Published laboratory reports are available for selected lots. Check each report for its result and stated method. For research purposes only.

About AHK-Cu 100mg
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.
Product Specifications
- Purity: ≥98% (supplier batch spec)
- Form: Lyophilized powder
- Sequence: Ala-His-Lys + Cu(II)
- CAS: 767286-83-9
Storage: -20C, protected from light; reconstitute in sterile water and use within 4 weeks at 4C. Shipped to a ≥98% supplier batch specification; selected lots are independently tested by Janoshik Analytical (HPLC + mass spectrometry), searchable by batch code at certapeptides.com/verify.

Researcher Confidence
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: you'll see the independent report we have published for that lot, if there is one, or the supplier's batch specification. If we have withdrawn a lot, it is marked there as withdrawn, with the reason. If yours is, 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, Iceland). 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 ANPC/ODR escalation available. Contact us at support@certapeptides.com.
