GHRP-2 Dosage Calculator
GHRP-2 is a growth-hormone-releasing peptide studied as a GH secretagogue in research settings. It is an investigational compound and is not FDA-approved.
Enter the milligrams on your vial, the bacteriostatic water added, and your dose in micrograms. The calculator returns the exact draw volume and the mark on a U-100 insulin syringe (1 IU = 0.01 mL).
The GHRP-2 dosage chart shows how commonly-referenced dose points translate to a draw at your vial size and water volume. Every figure is illustrative arithmetic, not a recommendation.
Tip: adding 2.50 mL of bacteriostatic water would put this dose on a clean, easy-to-read mark on a U-100 insulin syringe.

GHRP-2 Dosage Chart
Commonly-cited dose points (commonly-cited research range) at a 5 mg vial reconstituted with 2 mL of bacteriostatic water. The volume and syringe columns are computed from those inputs — illustrative math, never a dose recommendation.
| Example dose | Volume to draw | U-100 syringe | Notes |
|---|---|---|---|
| 100 mcg | 0.040 mL | 4 IU | — |
| 200 mcg | 0.080 mL | 8 IU | — |
| 300 mcg | 0.120 mL | 12 IU | — |
How to use this calculator
- Vial size — the milligrams printed on your GHRP-2 vial (commonly 5 or 10 mg).
- Bacteriostatic water — how much you add to dissolve the powder. More water = a larger, easier-to-read draw at the same dose.
- Dose — the amount you intend to draw, in micrograms. This is your number, not a recommendation.
- Read the IU mark — on a U-100 insulin syringe, 1 IU = 0.01 mL. The calculator shows the exact tick to fill to.
GHRP-2 FAQ
- How do I reconstitute GHRP-2?
- Add bacteriostatic water down the wall of the vial and let the powder dissolve without shaking. Use the calculator above to see the resulting concentration and the exact U-100 insulin-syringe units for your dose.
- How many units is a 100 mcg GHRP-2 dose?
- It depends on concentration. A 5 mg vial reconstituted with 2 mL yields 2,500 mcg/mL, so a 100 mcg dose is 0.04 mL, which is 4 IU on a U-100 insulin syringe. Adjust the water volume to move to a rounder mark.
- Is GHRP-2 FDA-approved?
- No. GHRP-2 is an investigational research compound and is not FDA-approved. The information here is educational, not medical advice, and not a dose recommendation.
- How is reconstituted GHRP-2 stored?
- Reconstituted peptide is generally refrigerated (about 2–8 °C) and protected from light; the dry powder is kept frozen. Follow the storage guidance for your specific product.
