if you use it as directed you'll be good. try the sprays they worked good for me. Don't expect steriod like gains though. I gained about four or five pounds. My strengh did go up.
The question is after you were done, how much of it did you keep. I think with any pro-hormone, or steroid gaining mass is as simple as constantly eating right, and working out hard. The difficult comes into play, after one has stopped using them.
Prohormones work for me(Adrospray anyways). I don't know if it has to do with my age(30), but at 19 you probably won't see anything unless your T leves are low which I doubt. High protein, glutamine and creatine is top 3 for natural lifters.
