How much muscle mass can you build on steroids alone?
"No shock, the placebo group had no change in anything. Training alone got the guys four and a half pounds LBM in 10 weeks. But steroids alone worked better: 6.6 pounds LBM in the same 10 weeks. With just one shot in the butt every week. Clearly training and exercise was synergistic and the third group gained close to what you’d predict from adding steroids and training alone together. But steroids alone built more muscle than training alone and just as much strength."
