PEG-MGF
Pegylated mechano growth factor
A polyethylene glycol conjugated MGF variant designed to extend a half-life measured in minutes into days.
How it works
PEGylation shields the peptide from protease degradation and renal clearance, so satellite cell signaling persists systemically rather than staying local.
What research has shown
Comparative animal work reports longer exposure and greater systemic effect than unmodified MGF.
Reported ranges in the literature
Low end
200 mcg twice weekly
Optimal
200 to 400 mcg twice weekly
High end
500 mcg twice weekly
Frequency reported in the literature: Two to three times weekly
Protocol duration and pairing
Typical study duration
4 to 6 weeks; pegylation extends the window versus native MGF.
