PEG-MGF (5mg)

PEG-MGF is a long-acting research peptide derived from MGF (Mechano Growth Factor), a splice variant of IGF-1, which is produced locally in muscle tissue in response to stress or damage to activate satellite cells for repair and hypertrophy. While natural MGF acts locally for a short time, PEG-MGF is modified to last longer in the bloodstream, providing extended recovery signals.
