Please can someone help me? My partner started taking testosterone 400 about a month ago. Now I know nothing about steroids so don't know if this will be harming him. The thing is he's changed so much in a matter of weeks and I've been with him for 7 years, he's got so indifferent about us and just doesn't seem to care. He's only taking 1 mil a week and said this isn't enough to make him change is this correct?
