MGF 2mg
GrowthMGF (Mechano Growth Factor) is a splice variant of IGF-1 that skeletal muscle produces locally in response to mechanical loading or damage — an autocrine/paracrine signal, not a systemic hormone. It's studied for activating satellite cells (muscle stem cells), the process muscle repair and hypertrophy depends on.
How is MGF different from IGF-1 LR3?+
IGF-1 LR3 circulates systemically and has a long half-life. MGF is produced locally by muscle tissue itself in response to damage or mechanical stress, acting where it's made rather than throughout the body.
Is MGF FDA-approved?+
No. It is not an approved drug and is sold for research use only.
What's the difference between MGF and PEG-MGF?+
PEG-MGF is the pegylated form — polyethylene glycol chains extend its half-life from minutes to roughly 24 hours, making it more practical to dose in a research setting.
