Hi:
Just wanted to ask that if "joe Weiders Mega mass" is usefull for building lean musles or not.
plz help , your help will be appreciated.
i am new to these suplement things.
plz guide me.
for lean msucle mas you just have to brun what you consume in order not to gain fat. sure it can help you but don´t exceed your caloric needs if lean muscle mass is your goal.
