AHK-Cu reconstitution calculator

AHK-Cu at a glance

100mg vial + 10mL BAC water = 10 units = 1mg — Frequency: daily — Best taken: morning, fasted

What it does

• A copper tripeptide related to GHK-Cu, studied for skin repair, collagen support, and anti-aging effects.
• Commonly used in cosmetic formulations, both topically and via injection in research settings.
• Limited independent human data compared to GHK-Cu — much of its reputation is inherited from the better-studied parent compound.

Like its parent compound GHK-Cu, AHK-Cu binds copper tightly. Copper-chelating medications (penicillamine, trientine — used for Wilson's disease) work directly against it, and combining the two can produce unpredictable copper levels for both the drug and the peptide. Anyone with a copper-metabolism disorder should avoid it.

Notes

All vial sizes reconstitute to 10mg/mL (100mcg/unit) so the syringe reads the same regardless of size.

Side Effects

• Mild redness, itching, or tingling at the site.
• Temporary extra hair shedding at the start — follicle cycling, settles in weeks.
• Injection site swelling in ~20-30% of uses, resolving in 1-3 days.
• Theoretical copper toxicity if also supplementing copper.

AHK-Cu vial sizes and concentrations

Standard water for each AHK-Cu vial size in the Dosify Me data, and the concentration it gives. One unit is 0.01 mL on a U-100 insulin syringe.

Worked example for AHK-Cu

1. The example vial: 100 mg of AHK-Cu, mixed with 10.00 mL of bacteriostatic water.
2. Concentration: 100 mg ÷ 10.00 mL = 10 mg/mL.
3. One syringe unit is 0.01 mL, so it holds 10 mg/mL × 0.01 mL = 0.1 mg (100 mcg).
4. Example quantity: 1000 mcg = 1 mg.
5. Volume: 1 mg ÷ 10 mg/mL = 0.1 mL.
6. Syringe reading: 0.1 mL × 100 = 10 units.

Frequently asked

How many units is 1 mg of AHK-Cu?

At 10 mg/mL (the concentration every vial size mixes to), 1 mg of AHK-Cu is 10.0 units on a 100-unit insulin syringe (0.100 mL).

How many units is 2 mg of AHK-Cu?

At 10 mg/mL (the concentration every vial size mixes to), 2 mg of AHK-Cu is 20.0 units on a 100-unit insulin syringe (0.200 mL).

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

10.00 mL, which gives 10 mg/mL. Other vial sizes use proportionally more or less water so the syringe reads the same.

How often is AHK-Cu taken?

Daily. Morning, fasted Typical cycle: 4 weeks on, ~2 weeks off; repeat 2–3×/year.
