MGF
Also known as: Mechano Growth Factor, IGF-1Ec, IGF-1 Eb (rodent splice variant)
MGF is a catalog-expanded peptide entry in ProtoComp's source-backed compound corpus. It is included for search, calculator math, stack awareness, and future research curation based on expand compound catalog, local_seed. Published dosing, cycle length, and clinical-use claims are intentionally left null until compound-specific evidence is reviewed.
No published dosing data available.
No published cycle data available.
No published human dosing trials. The endogenous splice variant exists in human muscle, but synthetic MGF protocols are not supported by peer-reviewed dose-finding data.
Contraindications
- • Active or history of malignancy (theoretical, mechanism-based)
Common side effects
- • Insufficient human data to characterize
Serious risks
- • Theoretical risk of accelerating occult malignancy (IGF-1 axis activation)
- • Long-term safety unknown
Drug interactions
- • Insufficient human data
Pregnancy / breastfeeding
Avoid — no human safety data
- MGF is a splice variant of IGF-1 (IGF-1Ec in humans), not a separate growth factor
- Synthetic MGF marketed for muscle repair has very short half-life and is largely degraded systemically — anabolic claims rest on rodent data
