About
MGF (also called IGF-1Ec) is what your muscle makes when you load it, a splice variant of the IGF-1 gene transcribed in response to mechanical stress. The role it plays endogenously is to activate satellite cells, the resident stem cells that fuse with damaged fibres to drive hypertrophy.
Read the full research guideWhy people choose it
- Strong local hypertrophy signal in the injected muscle. Satellite cell activation at the source
- No systemic IGF-1 elevation, so no hypoglycaemia risk and no whole-body mitogenic exposure
- Useful for rehab work on weakened or lagging muscle groups
- Pairs with the rest of the GH/IGF axis without compounding the systemic IGF-1 load
