Alright, I just got back from a shitty workout at the gym and I'm looking for some insight..I'm in my third week of PCT for my first cycle(8 week cycle). My PCT is 3 weeks and looks like this: 100 mg Clomid ed weeks 1-2, 40 mg Nolva ed weeks 1-2, 20 mg Nolva ed week 3, .25 mg Letrozole week 3. I am also running Clen that I started in week 2. I'm supplementing with tribulus, tons of glutamine, bcaa's, creatine, and CLA. Basically everything but the kitchen sink.. My question is...I've noticed for the past week or so that lactic acid burn gets so bad that it hinders my workout. I have to cut my sets well short of muscle failure because it hurts so much. I feel the burn mostly in the smaller assisting muscles. I hit chest/back today and on my rows, it was my rear delts that burned out quick, on lat pulls, my lats felt like they were disintegrating, and on flyes, it was my front delts. Is it possibly because of the Clen? I don't know, but I need to do something about it because it's debilitating...please help!!
