Calculators / GHRP-2 dose charts

GHRP-2 dose charts (mg → U-100 units)

Units to draw on a standard U-100 insulin syringe, for each common GHRP-2 vial size and BAC-water volume. Doses shown reflect ranges reported in published research — they are reference points for the math, not recommendations. For other numbers, use the live calculator.

5 mg vial

Dose+ 1 mL water (5 mg/mL)+ 2 mL water (2.5 mg/mL)+ 3 mL water (1.6666666666666667 mg/mL)
100 mcg2 u4 u6 u
200 mcg4 u8 u12 u
300 mcg6 u12 u18 u

10 mg vial

Dose+ 1 mL water (10 mg/mL)+ 2 mL water (5 mg/mL)+ 3 mL water (3.3333333333333335 mg/mL)
100 mcg1 u2 u3 u
200 mcg2 u4 u6 u
300 mcg3 u6 u9 u

Formula: units = dose ÷ concentration × 100 · concentration = vial mg ÷ water mL · GHRP-2 half-life ≈ 30 min (GHRP-2 / pralmorelin PK (Asakura 2010, PMID 20662346); GH peak ~60 min then cleared)
