What is MGF (IGF-1 Ec)?
MGF, or Mechano Growth Factor (IGF-1 Ec variant), is a splice variant of IGF-1 that’s released in response to muscle damage or mechanical overload. Unlike IGF-1 LR3, which acts systemically, MGF is known for its local, site-specific anabolic effect—making it a powerful tool for those targeting muscle growth in specific areas.
It promotes satellite cell activation, muscle fiber repair, and rapid muscle regeneration, especially when injected directly into the muscle group being trained.
Key Benefits:
- ✅ Stimulates localized muscle growth and repair
- ✅ Activates satellite cells for muscle regeneration
- ✅ Enhances recovery after intense training or injury
- ✅ Can be used to bring up lagging muscle groups
- ✅ Works synergistically with IGF-1 LR3 for full-spectrum muscle development
- ✅ Fast-acting and non-systemic
Who Should Use MGF?
MGF is ideal for bodybuilders looking to bring up weak points, athletes recovering from injury, or anyone focused on targeted hypertrophy. Best used post-training and injected intramuscularly in the trained area for optimal results.
Format: 5mg lyophilized peptide vial
Suggested Use: Inject 200–400mcg directly into target muscle post-workout, 1x daily for up to 4 weeks. Can be cycled or stacked with IGF-1 LR3.
Storage: Store in refrigerator once reconstituted
