GHRP-2 Reconstitution & Dosing
Quick answer: mix a 5 mg vial of GHRP-2 with 2 ml of bacteriostatic water. That gives 2.50 mg/ml, so a typical 200 mcg dose is 8.0 units on a U-100 insulin syringe — about 25 doses per vial. Reported protocols range 100 mcg–300 mcg, 1–3x daily.
GHRP-2 is a second-generation GH secretagogue, stronger than GHRP-6 with less hunger stimulation. Largely superseded by Ipamorelin in modern protocols but still widely referenced. Full overview: what is GHRP-2? →
