MGF (without PEG)

Mechano Growth Factor — short-acting IGF-1 splice variant that activates local satellite cells right at the injection site.

MGF is the splice variant of IGF-1 your muscles make locally right after they've been mechanically stressed — i.e., after a hard set. It's the "repair this exact spot" signal that wakes up satellite cells (muscle stem cells) to rebuild the fibres you just worked. Injected straight into a trained muscle immediately post-workout, it concentrates that repair signal where you want it. Its half-life is only minutes, so timing is everything — and that brevity is also a safety feature, keeping the effect local instead of systemic.

Dose

100–200 mcg site-injected, immediately post-workout.

Reconstitute

2 mg + 2 mL = 1 mg/mL. 10 units = 100 mcg.

Schedule

2–4 week loads.

Half-life

~5–7 minutes (very short — must be timed precisely).

Timing

Immediately post-workout, into the trained muscle.

Risks

Theoretical cancer risk like IGF-1. Very local due to short half-life — limits systemic exposure.
