If you are seriously going to pursure being a professional body builder, you will have to get into steroids . If you are not going to do body building as a professional, wait until you are older.
At the age of 20 I trained hard offseason (I wrestled in HS and college). I could put on 10lbs of muscle over the summer break (3 months) and I was not pushing muscle gain or eating for it. I was pushing myself in the gym, though and that made a big difference. Push yourself hard in the gym first. At 6’1" and 195 lbs you either are not going about your weight training and diet correctly or you simply don’t have the genetics for body building. If you don’t have the genetics then forget any dreams of being a TrueMaxder. If you do have the genetics but are not pushing doing the workouts then learn to workout and eat properly first. Steroids will give you gains, but if you don’t throwup during squats, if you don’t forcefeed that extra 80g of protein a day, then you won’t benefit from the steroids that much.
