It will effect it whether you want to accept it or not. LOL. I too was a daily puffer for awhile. I was on a test cycle and did both for almost three months. I found that the weed made me highly unmotivated. It also made my recovery feel like it was weaker (even with all the proper diet, etc). I guess it was like I could feel the muscles turning soft to quickly. It also put me out of breath more than if I didn't smoke on those days. So it would interfere with endurance. I still put on 20 lbs of muscle in those 3 weeks. But it probably should have been more like 30!! The THC in the dope turns into estrogen. So after your high comes down you start to lose. So it turns your muscles softer and less recovery is possible. That's even on TEST !!! So I can't imagine just going normal. The effects should be even harder on you. But I can relate to wanting a puff sometimes to unwind. I think if your going to do it, you need to keep it at maybe just once a week. And maybe take nolvadex if you do it. To block more of the estrogen. It absolutely , positively, will hurt your gains smoking the green, lol !! I can speak from experience. But, everyone is different. Good luck !
