PEG-MGF 2mg
GrowthPEG-MGF is the pegylated (polyethylene-glycol-attached) form of Mechano Growth Factor, an IGF-1 splice variant muscle tissue produces locally after mechanical stress or damage. Pegylation extends its half-life from minutes to roughly 24 hours, making it more practical to dose than unmodified MGF in a research setting, at the cost of the very short, sharply localized action the native form has.
Is PEG-MGF FDA-approved?+
No. It is not an approved drug and is sold for research use only.
Why pegylate MGF at all?+
Unmodified MGF's half-life is only minutes, which is impractical to dose in most research protocols. PEGylation extends that to roughly a day, at some cost to how sharply localized its original signal was.
How strong is the evidence behind it?+
Much of what circulates about PEG-MGF online extends well beyond what's actually been studied — treat specific performance claims with real skepticism rather than taking them at face value.
