I like a cycle that is a little longer. You can only gain muscle so fast. no matter what you take, so in 20 wks, I believe I gain more real muscle than in shorter cycles. But of course, the longer you are on, the longer it takes to recover after you come off. So it's up to you brother. There is some truth about making better gains in the start. Over time, gains can slow as your body gets used to the gear, but you should still be able to gain muscle. Most of the weight you see in the first 8 wks is going to be fluid and blood, building up and filling out your muscle. So some of what you see at the start isn't really muscle to begin with
