I'm a pretty big guy and have been using steroids for a few years now. I'm 230 pounds at 6 2 and a bodyfat around 13%. I can bench press a Buick and am very strong. My current girlfriend and I started playing tennis together on this cycle of Test 500 and masteron 400 and I have a very hard time chasing the ball. Is this normal? I have to pretend I am tying my shoe between points i am so out of breath.
