MGF (Mechano Growth Factor)- Summary
- Noopept is a potent dipeptide-derived nootropic from Russia, structurally related to piracetam but estimated to be 1,000 times more potent by mass. It enhances memory consolidation, learning, and recall while providing neuroprotection via BDNF and NGF upregulation.
- MGF (Mechano Growth Factor) is a splice variant of IGF-1 that is locally produced in muscle tissue in response to mechanical damage from exercise. It activates muscle satellite cells (stem cells) to proliferate and repair damaged fibers, making it specifically targeted at exercise-induced hypertrophy.
- Half-Life
- ~5–10 minutes but metabolite (CPG) effects last hours
- Native MGF: minutes. PEG-MGF: ~3 days
- Admin Route
- Oral, Sublingual, Intranasal
- SubQ, IM
