AHK-Cu
Alanyl-histidyl-lysine with copper; used in cosmetics mainly for hair-follicle support.
Cosmetic ingredient; not an approved drug.
Look it up on Wikipedia51 listings across 27 independently tested vendors, ranked by price per milligram after coupon codes anyone can use. Vendors you can only order from by message are hidden. 4 unusually cheap listings are marked “check vials” and left out of the cheapest pick.
Some links here are affiliate links: if you buy through one, this site may earn a commission at no extra cost to you. Prices, rankings and plans are worked out the same way whether or not a vendor pays one.
Not an FDA-approved drug and not nominated for FDA's 503A bulks list, so US pharmacies can't legally compound it.

Doses studied in research Animal or lab studies only
What was given to people (or animals) in published studies and official labels, each linked to its source. This is not a recommendation: study products, purity and supervision differ from research-grade vials.
Animal studies: The only direct study (2007) applied AHK-Cu at 10^-12 to 10^-9 M to isolated human hair follicles ex vivo and to cultured dermal papilla cells; no animal dosing or human trials of AHK-Cu were found.
Laboratory concentrations in cell or organ culture do not translate to any human dose. Human 'copper peptide' hair studies concern GHK-Cu or multi-ingredient products, not AHK-Cu.
What the research says
AHK-Cu has almost no published research: a single 2007 laboratory study found it lengthened human hair follicles ex vivo and stimulated dermal papilla cells, and a related vitamin C-conjugated AHK peptide was active in cell culture. No animal efficacy studies or human trials of AHK-Cu were found; human 'copper tripeptide' hair studies concern GHK-Cu or multi-ingredient mixtures.

The effect of tripeptide-copper complex on human hair growth in vitro.Cells / labIn vitro / ex vivo study of AHK-Cu (10^-12 to 10^-9 M)
AHK-Cu (10^-12 to 10^-9 M) stimulated elongation of human hair follicles ex vivo and proliferation of cultured dermal papilla cells, with a higher Bcl-2/Bax ratio; the reduction in apoptotic cells was not statistically significant.
Key resultAHK-Cu stimulated hair follicle elongation and dermal papilla cell proliferation; 10^-9 M raised the Bcl-2/Bax ratio and reduced cleaved caspase-3 and PARP, while the reduction in apoptotic cells was not statistically significant
Study details
- Studied
- Human hair follicles ex vivo and cultured dermal papilla cells
- Compared with
- Untreated
- Main outcome
- Hair follicle elongation, dermal papilla cell proliferation and apoptosis markers
- Authors' conclusion
- AHK-Cu promotes growth of human hair follicles, possibly by stimulating dermal papilla cell proliferation and preventing apoptosis.
- Limitations
- Ex vivo and cell culture only; no in vivo data.
-
Vitamin C-linker-conjugated tripeptide AHK stimulates BMP-2-induced osteogenic differentiation of mouse myoblast C2C12 cells.Cells / labIn vitro study of Vit C-linker-conjugated AHK tripeptide (not AHK-Cu) with BMP-2
A vitamin C-conjugated AHK tripeptide (no copper) enhanced BMP-2-induced osteoblast differentiation of mouse C2C12 cells without significant cytotoxicity; not a test of hair or skin effects.
Study details
- Studied
- Mouse C2C12 myoblast cells
- Compared with
- BMP-2 alone
- Main outcome
- Proliferation, alkaline phosphatase, Smad1/5/8 and MAPK signaling, osteogenic gene expression
- Authors' conclusion
- Vit C-AHK enhanced osteoblast proliferation and differentiation through Smad1/5/8 and MAPK signaling without significant cytotoxicity, providing data for peptide-based bone-regenerative agents.
- Limitations
- Cell culture only; a vitamin C-conjugated AHK without copper, not AHK-Cu.

AHK-Cu: questions people ask
What is AHK-Cu?
Copper tripeptide. Alanyl-histidyl-lysine with copper; used in cosmetics mainly for hair-follicle support.
How much does AHK-Cu cost?
The cheapest AHK-Cu from an independently tested vendor is $0.007 per mg (Andy Peps Studio, AHK-cu Bulk 500g, $3,500.00). Across 51 listings from 27 vendors the median is $0.120 per mg.
Where can I buy AHK-Cu?
27 vendors tested by Finnrick sell AHK-Cu. The cheapest per mg right now: Andy Peps Studio ($0.007), Baohua Dongnuo Biotechnology BHD ($0.007), LN Peptides ($0.007). 3 of them publish a lab report (COA) for AHK-Cu; compare lab scores and reports in the table above before buying.
How much bacteriostatic water for 100 mg of AHK-Cu?
Adding 2 mL of bacteriostatic water to a 100 mg vial of AHK-Cu gives 50 mg/mL: each 10 units on a U-100 insulin syringe holds 5,000 mcg. With 1 mL it's 100 mg/mL (10,000 mcg per 10 units); with 3 mL, 33.333 mg/mL (3,333.3 mcg per 10 units). More water makes small amounts easier to measure. Mixing charts: 50 mg, 100 mg, 1,000 mg.
Is AHK-Cu FDA approved?
Cosmetic ingredient; not an approved drug.
Can AHK-Cu be compounded in the US?
Not an FDA-approved drug and not nominated for FDA's 503A bulks list, so US pharmacies can't legally compound it. Compounding status for every peptide.
Does AHK-Cu work? What does the research say?
Evidence grade D (little or no evidence), from 2 papers: Only one ex vivo hair-follicle/cell study of AHK-Cu plus a cell study of a copper-free AHK conjugate; no animal or human data. AHK-Cu has almost no published research: a single 2007 laboratory study found it lengthened human hair follicles ex vivo and stimulated dermal papilla cells, and a related vitamin C-conjugated AHK peptide was active in cell culture. No animal efficacy studies or human trials of AHK-Cu were found; human 'copper tripeptide' hair studies concern GHK-Cu or multi-ingredient mixtures. See the papers.
What dose of AHK-Cu was used in studies?
AHK-Cu is tested only in animals or cells. The only direct study (2007) applied AHK-Cu at 10^-12 to 10^-9 M to isolated human hair follicles ex vivo and to cultured dermal papilla cells; no animal dosing or human trials of AHK-Cu were found. These are amounts used in published studies or official labels, not a recommendation.
