I play football in college and have a chance of getting on with some teams in the cfl and arena league.I'm 6"1 1/2 235, my body fat is a little high, so I was wondering about clen. I asked a friend for some clenbuterol and he gave me this bottle called Oxyflux Clenbuterol by farmaceuticos Rayere. I was just wondering if this stuff was legitimate and how I should take it.
