Human tissue is not a human
The phrase that does the damage here is human hair follicles. Quoted on its own it reads like a trial, and the study was nothing of the kind. The follicles were removed, kept alive in a bath, and watched.

U-100 insulin syringe · 1 mL · lines every 2 units · 1 unit = 0.01 mL
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

How to use the calculator
- STEP 1

Enter the water you added
- STEP 3
Enter the dose you want to convert
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 a 10 mg AHK-Cu vial
Each row starts with the same 10 mg vial and changes only the amount of water. More water makes the mixture less concentrated, so the same dose uses more syringe units.
◆ How the water amount changes the resultdose used: 500 mcg
| Water added | 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 vial, water 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.
One paper, about a dish, and one letter away from a different molecule
The indexed literature on this peptide is a single study, published almost twenty years ago. It treated hair follicles kept alive outside a body, and cells grown from the base of a follicle. Nobody has been given it in a published study since, so this tool has no human quantity to convert.
A strength in a bath is not an amount in a person
The only figures the literature holds for this peptide describe how concentrated that liquid was. Turning one into a quantity someone could receive needs to know how a body spreads and clears it, and nobody has measured that.
Do not read across from the copper peptide next door
GHK-Cu differs from this molecule by one amino acid and by an entire body of evidence. It has controlled trials in people, decades as a cosmetic ingredient, a regulator’s written assessment of the injectable form, and a committee date ahead of it.
Numbers do circulate, and their only source is a shop
Amounts for this peptide are easy to find. Every one traced by this project led to a page selling it. That is not a source, and repeating it without the link does not make it one.
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.
| U-100 line | Volume | Mass (mcg) | Mass (mg) |
|---|---|---|---|
| 10 u | 0.10 mL | 500 mcg | 0.5 mg |
| 20 u | 0.20 mL | 1,000 mcg | 1 mg |
| 30 u | 0.30 mL | 1,500 mcg | 1.5 mg |
| 40 u | 0.40 mL | 2,000 mcg | 2 mg |
| 50 u | 0.50 mL | 2,500 mcg | 2.5 mg |
| 60 u | 0.60 mL | 3,000 mcg | 3 mg |
| 70 u | 0.70 mL | 3,500 mcg | 3.5 mg |
| 80 u | 0.80 mL | 4,000 mcg | 4 mg |
| 90 u | 0.90 mL | 4,500 mcg | 4.5 mg |
| 100 u | 1.00 mL | 5,000 mcg | 5 mg |
How the math works
- Concentration — divide the amount in the vial by the water you added: 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.
