Animal studies only

Almost all the research is in animals. We do not know if the same thing happens in people.

Also called Mechano Growth Factor / IGF-1Ec

A short piece of a natural growth factor, studied in animals for muscle repair.

The basics

What is it?
MGF is a variant of IGF-1 that muscle makes after damage. Note: PEG-MGF is a pegylated (chemically modified, longer-lasting) version. PEG-MGF and plain MGF are not interchangeable — they behave differently in the body and the research on one does not carry over to the other.
