MGF (Mechano Growth Factor, IGF-1Ec)
IGF-1 Splice Variant (Local Repair Peptide)
/WHAT_IT_IS
MGF is the IGF-1Ec splice variant expressed in response to mechanical overload. As a short, locally acting peptide, it’s studied for activating muscle satellite cells, promoting repair, and remodeling damaged tissue.
/USAGE
Investigated for post-exercise or post-injury muscle regeneration, myoblast activation, and localized tissue repair models.
/MECHANISM_OF_ACTION
Acts in an autocrine/paracrine manner to upregulate satellite-cell activation and proliferation, modulate myogenic regulatory factors, and initiate early-stage muscle repair distinct from systemic IGF-1 signaling.
Reported Benefits
- +Promotes satellite cell activation and proliferation
- +Supports localized muscle repair/remodeling
- +May reduce recovery time after mechanical stress
- +Complements later-stage IGF-1–mediated hypertrophy pathways
Reported Side Effects
- −Injection-site redness or irritation
- −Transient localized swelling/pump sensation
- −Rare dizziness or fatigue
- −Theoretical risk of disproportionate tissue growth with improper use

/RESEARCH_NOTES
Non-PEG MGF is short-acting and typically timed acutely post-stimulus to model early repair. Distinct from PEG-MGF, which extends half-life/systemic exposure. Monitor study endpoints such as CK, local circumference/ultrasound, and functional recovery. Consider sequencing with IGF-1 or GH secretagogues for later hypertrophy phases.
