What is the half-life of MGF (Mechano Growth Factor)?
MGF (Mechano Growth Factor) has a reported half life of ~5-7 minutes, given subcutaneous, often near worked muscle. That is why it is typically dosed post-workout, 1x daily. A shorter half life means more frequent dosing to keep blood levels steady, a longer one lets you space doses further apart.
Quick facts
- Half-life: ~5-7 minutes
