I am having trouble with my quads and hams being extremely weak after a workout. I know muscle fatigue is normal, but I just did a few squats today, with no wieght, and later tonight, my legs feel like I have done an all out workout. I'm kind of concerned that something might be wrong. Has anyone had any kind of experience like this? Any input would help. I have been using test cyp at 400 mg per week. Could this have anything to do with it?
