Off days only, or about 12hrs post WO. no more than 3x a wk.
regular mgf is way way stronger then PEG-MGF. the peglation (sp) which makes the half life 16-24hrs makes it a lot weaker.
So if your using PEG dose it high. if your using regular, use it 2-3x ED, no more than 3 days a wk. using igf with it makes a world of difference.
