I was going to use it just for the benefit of helping to keep my knees and elbows from disintegrating (not really that), but I haven't always responded favorably to it in terms of building muscle and size. This time around, I wanted to concentrate on muscle and size for a change so I got together as many anabolic elements as I could that I know I respond to. I'm old enough though, I should probably always throw it in just for the joint protection. As far as the original topic, hell YES, that happens to me. Same with tren. Of course with either of them, they make you horny, but then it takes forever to get it out or you go limp in the process, lol.
