Gonadorelin Reconstitution & Dosing
Also known as: GnRH
Quick answer: mix a 2 mg vial of Gonadorelin with 2 ml of bacteriostatic water. That gives 1.00 mg/ml, so a typical 100 mcg dose is 10 units on a U-100 insulin syringe — about 20 doses per vial. Reported protocols range 100 mcg–200 mcg, 2–3x weekly (TRT-support protocols).
