Muscle Growth & Recovery
PEG-MGF
PEGylated Mechano Growth Factor
A pegylated splice variant of IGF-1 that activates muscle satellite cells in response to mechanical loading.
Compounded · 503A Pharmacy
Mechanism of action
Activates dormant satellite cells, promoting myoblast proliferation and fusion into existing muscle fibers. PEGylation extends half-life.
Studied uses
- ✓Post-training muscle recovery
- ✓Lean muscle accrual research
- ✓Age-related sarcopenia investigation
Research highlights
- · Increased muscle fiber cross-sectional area in rodents
- · Early-stage human work in muscular dystrophy
Side effects & cautions
- · Localized post-injection swelling
- · Theoretical concerns with cellular proliferation pathways
