GHK-Cu Dosage Calculator
A copper-binding tripeptide studied in skin, hair, and tissue-repair research.
Total amount printed on the vial label.
Changes concentration only — your dose stays the same.
2000 mcg = 2 mg
1.0 mL (100-unit) insulin syringe · smallest mark = 2 units · check yours, gradations vary by brand
Show the math
- Concentration: 50 mg ÷ 5 mL = 10.00 mg/mL (10000 mcg/mL)
- Dose volume: 2000 mcg ÷ 10000 mcg/mL = 0.200 mL
- Syringe units: 0.200 mL × 100 = 20 units
How much water should I add?
The same 2000 mcg dose from your 50 mg vial, at each water volume. More water spreads the dose over more units, which is easier to read accurately. Tap a row to use it.
Calculated on a U-100 insulin syringe (100 units = 1 mL). This is reconstitution arithmetic for GHK-Cu, not a dosing recommendation. Verify against your product label and a qualified professional.

| Vial size | Bac. water | Concentration | Per unit (0.01 mL) |
|---|---|---|---|
| 50 mg | 5 mL | 10.00 mg/mL | 100.0 mcg |
| 100 mg | 5 mL | 20.00 mg/mL | 200.0 mcg |
About GHK-Cu dosing
GHK-Cu (GHK-Cu) is a copper-binding tripeptide studied in skin, hair, and tissue-repair research. It is commonly sold in 50 mg, 100 mg vials. Commonly-cited community and research protocols reference a range of 1,000–3,000 mcg, daily in many cited protocols. Sold in large (50–100 mg) vials; use more bac water to keep the concentration workable.
Remember that the number of syringe units for any dose depends entirely on how much bacteriostatic water you add. The calculator above is pre-filled with a common setup for GHK-Cu; adjust the inputs to match your own vial and the units update instantly.

GHK-Cu calculator — FAQ
How do I reconstitute GHK-Cu?+
Sold in large (50–100 mg) vials; use more bac water to keep the concentration workable. Add your chosen amount of bacteriostatic water to the vial, swirl gently (never shake), and use the calculator above to convert your target dose into insulin-syringe units.
What is a common GHK-Cu dose?+
Commonly-cited protocols reference 1,000–3,000 mcg, daily in many cited protocols. These are references for the arithmetic, not a prescription — confirm with your product label and a qualified professional.
How many units of GHK-Cu should I draw?+
That depends on your vial size and how much bacteriostatic water you added. Enter both into the calculator above along with your dose and it shows the exact units on a U-100 insulin syringe.
