PEG-MGF Reconstitution & Dosing

Also known as: Pegylated Mechano Growth Factor

Quick answer: mix a 2 mg vial of PEG-MGF with 2 ml of bacteriostatic water. That gives 1.00 mg/ml, so a typical 200 mcg dose is 20 units on a U-100 insulin syringe — about 10 doses per vial. Reported protocols range 200 mcg400 mcg, 2–3x weekly, often post-training.

PEG-MGF is a pegylated version of Mechano Growth Factor, the IGF-1 splice variant expressed after mechanical muscle damage, studied for repair and satellite-cell activation. Full overview: what is PEG-MGF? →

FAQ

How much bacteriostatic water do you add to PEG-MGF?+

Most protocols mix a 2 mg vial of PEG-MGF with 2 ml of bacteriostatic water. This gives 1.00 mg/ml, so a typical 200 mcg dose is 20 units on a U-100 insulin syringe. More or less water is fine — it only changes the volume you draw, not the dose.

What is a typical PEG-MGF dose?+

Commonly reported PEG-MGF protocols use 200 mcg to 400 mcg, 2–3x weekly, often post-training, administered via subcutaneous injection. These are reference figures from published protocols, not medical advice — individual use should be guided by a healthcare provider.

How many doses are in a 2 mg vial of PEG-MGF?+

At 200 mcg per dose, a 2 mg vial contains about 10 doses, regardless of how much water you add.

How should PEG-MGF be stored?+

Reconstituted: refrigerate, typically used within 4 weeks.
