Can someone help me here... Self proclaimed newby.

I have been taking Anevol... My first week and a half I put on 5 - 6 pounds, I felt like a freakin animal in the gym, I was loving it. Iam now 2 - 3 weeks in and feel like normal. Maybe even my libido has slowed down? I am about to quite the cycle start my PCT and look for somthing where I can be an animal during the whole cycle. Any feedback would be greatly appreciated.
