How It Works
1. Concentration
Divide vial amount (mcg) by water volume (mL) to get concentration (mcg/mL).
2. Volume needed
Divide desired dose by concentration to get injection volume in mL.
3. Syringe units
Multiply mL × 100 to get U-100 syringe units (IU).
Example
- 5 mg vial + 2 mL water = 2.5 mg/mL
- Want 250 mcg (0.25 mg)?
- 0.25 ÷ 2.5 = 0.1 mL
- 0.1 mL = 10 units on a U-100 syringe

What is GHK-Cu?
GHK-Cu (Glycine-Histidine-Lysine copper) is a copper tripeptide naturally present in blood plasma, urine and saliva. Its concentration declines with age, making it a prime subject of dermatological research. It is one of the most studied peptides in skin biology, used as an in vitro research reagent. Its characteristic blue tint comes from the copper complex. Lyophilised product supplied with an independent certificate of analysis — not for human consumption.
