Mechano Growth Factor: the complete guide
Mechano Growth Factor (MGF) is a splice variant of IGF-1 (IGF-1Ec) produced locally in skeletal muscle in response to mechanical loading. Synthetic MGF is researched for targeted muscle-recovery and hypertrophy signaling.
How Mechano Growth Factor works
MGF's unique E-peptide domain activates local satellite-cell proliferation and muscle repair independent of IGF-1 receptor pathways. Its extremely short half-life dictates the post-workout, site-local administration pattern.
Typical Mechano Growth Factor dosage
Commonly reported research ranges: 100–200 mcg per injection, typically immediately post-workout.
Dose should always be individualized. Factors that influence it include bodyweight, research goal, tolerance, and specific compound batch. The information below is educational, not a prescription.
How to reconstitute Mechano Growth Factor
A widely used reconstitution for a 2 mg vial is 2 ml of bacteriostatic water. With a typical 100 mcg dose this works out to the unit count shown in the calculator below.
Half-life and administration frequency
Approximately 5–7 minutes (very short).
This half-life informs how often Mechano Growth Factor is typically dosed. Shorter half-lives usually mean more frequent dosing to maintain plasma levels; longer half-lives allow daily, weekly, or less-frequent administration depending on the compound.
Reported side effects
- Injection-site reactions
- Limited human safety data
- Potential local tissue effects incompletely characterized
This list reflects effects reported in available literature or user logs. It is not exhaustive. Adverse reactions should be discussed with a qualified clinician.
Common Mechano Growth Factor stacks
- IGF-1 DES
- HGH
Storage and handling
Lyophilized: refrigerated. Reconstituted: refrigerated, use within 7–14 days (short window — MGF is unstable).
FDA and regulatory status
Not FDA approved. Research use only in the US.
