well, this product is really work for me dude. I been taking it for 6 weeks, and I gained 24 pounds already. However, when I took it at the first week. My whole body felt so tired, and I eat twice as much as I usually do. But its getting family in the 2nd week and so on. I took creatine before, and creatine is just a f**king product that waste my money. But C9T11 is DIFFERENT, it help me jump from 162 pounds to 186 pounds in 6 weeks. More importantly, all the pounds I gained are muscle. I don't even have to train in the gym much like I did before, but my muscle is keep growing, growing, and growing. This product is also cheap, I'm sure you won't be disappoint if you try it.
