AHK-Cu Dosage Calculator & Chart

Two routes — topical serum or subcutaneous AHK-Cu can be used two ways, and they are not interchangeable. Most of the published copper-peptide work in this class is topical, which is why the serum route is listed first. The subcutaneous figures below mirror GHK-Cu, the closely related copper tripeptide — there is no AHK-Cu-specific injection trial, so treat those numbers as extrapolated from a structural analogue rather than established for this compound.

What we suggest instead. Pick one route and stay on it. For topical use, follow the serum steps below — the whole vial goes into one 30 mL bottle and nothing is injected. For subcutaneous use, reconstitute with bacteriostatic water instead and work from the dose table; the calculator on this page is set up for that route.

1Set Up Your Mix

33.333 mg/mL · 33333 mcg/mL

1. Pick your peptide

2. How much peptide is in the vial? It's printed on the label — usually something like 5 mg

3. How much sterile distilled water are you adding? More water makes each dose easier to measure

4. How much do you want per dose?

Your Answer — AHK-Cu

100 mg in 3 mL

100Doses In The Vial

100 mg ÷ 3 mL = 33.333 mg/mL → 1 mg ÷ 33.333 mg/mL = 0.03 mL → × 100 = 3 units

Looks good. Draw to 3 units on a 1 mL syringe. That is an easy amount to measure, and this vial gives you 100 doses.

Where this plan came from

Built from this peptide's dose range

Where this came from: Built from the doses listed for this peptide below — start at the lowest and step up, using the studies cited on this page. Nobody publishes a week-by-week plan for this peptide, so we built one: the doses are the researched ones shown below, and we simply put them in order from lowest to highest. Treat it as a starting point, not an official schedule.

Please read this. These numbers come from published research. They are here as reference, not as instructions. A lot of them come from lab studies rather than studies in people, and some of these peptides have never been given to a person at all.

Tissue Repair & Recovery

Also known as

Alanine-histidine-lysine copper peptide

Class

Cosmetic & Dermal

Route

Topical or subcutaneous

Half-life

Short systemically

Evidence tier

Limited

A copper-binding tripeptide, related to GHK-Cu but with a different amino acid sequence. Most of the published work is cosmetic and in-vitro, focused on hair follicle and dermal papilla models rather than systemic administration. Human data is limited to small cosmetic studies.

Common Questions — AHK-Cu

How much bacteriostatic water do I add to a 100 mg vial of AHK-Cu?

Adding 3 mL of bacteriostatic water to a 100 mg vial gives 33.3 mg/mL. That is the mix the subcutaneous figures on this page are worked out from. The topical serum route uses 1 mL of sterile distilled water instead — see the steps above. That is the mix every number on this page is worked out from — change the water figure in the calculator and all the draw amounts update.

What dose of AHK-Cu is used in research?

Published and reported figures for AHK-Cu cover a 0.05–0.1% topical formulation, and 1–3 mg subcutaneously, mirroring the closely related GHK-Cu. This site lists each figure with the source it came from rather than giving a single recommended number.

How many units on the syringe is a 1 mg dose of AHK-Cu?

At 33.3 mg/mL, a 1 mg dose is 3 units on a 1 mL U-100 insulin syringe. One vial at that mix gives about 100 doses.

How strong is the evidence behind these AHK-Cu doses?

AHK-Cu is graded limited. The figures are sparse — a single programme or community-reported numbers. We grade every compound on this site so you can weigh the numbers accordingly — the full method is on our editorial policy page.
