But a few people said they had major irritability and anger, and had to stop in
order to prevent getting in a fight. My boyfriend already has a little bit of a temper.
The main questions I want to know,
Is this stuff a healthy way to gain muscle? Or is it healthy to have in his diet, since he also drinks protein shakes after the workout?
Should this have any negative side effects, and how likely are they?
If this is a bad thing, what should he be doing?
