PEG-MGF

PEG-MGF (PEGylated Mechano Growth Factor) is a variant of IGF-1 that is produced in response to muscle damage. PEGylation extends its half-life from minutes to several hours, making it practical for use.

Mechanism of Action

Activates muscle satellite cells (stem cells) and promotes their fusion to existing muscle fibers for repair and growth. MGF is produced naturally in response to mechanical stress on muscles.

Typical Dosage (Research)

Research protocols typically use 200-400mcg injected into targeted muscle groups 2-3 times weekly, usually post-workout.

Intramuscular injection, ideally into muscles trained that day. Best administered post-workout when satellite cell activation is relevant.

Side Effects & Risks

Injection site soreness, potential hypoglycemia, and localized swelling. Generally well-tolerated.

Limited human research. May promote unwanted tissue growth. Quality and purity concerns with research products.

Who Uses PEG-MGF

Bodybuilders, athletes recovering from muscle injuries, those seeking targeted muscle development.
