MGF (Mechano Growth Factor)- Summary
- Oxytocin is a 9-amino acid neuropeptide produced in the hypothalamus with diverse roles in social bonding, trust, stress reduction, and sexual function. Exogenous administration is used therapeutically to improve social cognition, reduce anxiety, and enhance intimacy.
- 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
- ~3–5 minutes (IV); ~30–60 minutes (intranasal, CNS effects persist longer)
- Native MGF: minutes. PEG-MGF: ~3 days
- Admin Route
- Intranasal, SubQ, IV
