Draw to
10.0units
10.0 units on a U-100 insulin syringe · 1 mL · lines every 2 units, which is 0.10 milliliters. The draw lands on a syringe line.
10 mg ÷ 2 mL = 5.00 mg/mL
→ 50 mcg/unit · 500 mcg = 0.100 mL = 10.0 units
→ 50 mcg/unit · 500 mcg = 0.100 mL = 10.0 units

AHK-Cu is three amino acids holding a copper ion. It differs from the better-known GHK-Cu by a single amino acid, and the two get confused constantly. It is sold mainly for hair — thicker growth, less shedding — as powder for injection or in scalp serums.
One study of it exists in the indexed literature, published in 2007. It treated human hair follicles kept alive in a dish, not people. The follicles grew longer, and the cell-death finding the authors chased was not statistically significant. No trial registry lists it.
No completed controlled human trial has shown which dose works for AHK-Cu. There is no study-backed human dosing program to publish. Animal quantities are not converted into a human recommendation.

Examples using 10 mg of AHK-Cu
Each row uses 10 mg and the liquid volume shown. Dividing the amount by that volume gives the calculated concentration. The rows are arithmetic examples, not alternative product preparations.

| Bacteriostatic water | Concentration | Per U-100 unit | Draw for 500 mcg | Nearest syringe line |
|---|---|---|---|---|
| 1 mL | 10.00 mg/mL | 100.0 mcg | 5.0 u · 0.050 mL | 6 u · 20.0% off |
| 2 mL | 5.00 mg/mL | 50.0 mcg | 10.0 u · 0.100 mL | exactly 10 u |
The amount, liquid volume and dose shown here are the calculator’s starting example for AHK-Cu. Replace them with your own values. Every result in the table is calculated from those inputs.
The AHK-Cu hair study used tissue outside the body
The cited experiment studied human hair follicles kept outside the body and cells grown in a laboratory. Human tissue in a dish is not a trial in people. The study does not supply a human dose for this tool.

The published figures describe the laboratory liquid
The researchers tested concentrations around the tissue and cells. Those values do not describe an amount given to a person. A calculation would still lack the information needed to translate that setting into human exposure.
AHK-Cu and GHK-Cu have separate evidence
Their names differ by one letter, but the peptides have different amino-acid sequences. Findings about GHK-Cu cannot fill a missing AHK-Cu dose row. The tool therefore presents sample arithmetic without treating the related compound’s literature as a substitute.

Units to dose at 5.00 mg/mL
Mix 10 mg into 2 mL and one U-100 unit carries 50.0 mcg. The table shows how much peptide is in each numbered syringe line. These are conversion examples, not suggested doses.

How the math works
- Concentration — divide the amount entered by the liquid volume used in the calculation: mg ÷ mL = mg/mL. This tells you how many mg are in each mL.
- Volume — the dose divided by that concentration: dose ÷ (mg/mL) = mL.
- Units — on a U-100 syringe one unit is 0.01 mL, so mL × 100 = units. A U-40 unit is 0.025 mL, so the wrong barrel is a 2.5× error. That is why the calculator asks which one you have.
- Rounding gap — the exact draw against the nearest syringe line: |exact − nearest line| ÷ exact × 100 = % difference.
