I have been experiencing back pumps the last week and a half. They started a few weeks ago after doing deadlifts and back extensions. My lower back muscles get tight when doing just about anything. From mowing the lawn to loading plates on a barbell. I have done a search and it seems like a lot of people get them dbol. I am on an M1T cycle and have them. I have a theory on what causes them wanted to see what threst of you thought. I am thinknig that with dbol people tend to put on a lot of weight pretty quickly. I have gained 17lbs in 3 weeks with M1T. Could the tight back and pumps be caused by carrying around that extra weight pretty quickly. Like a pregnant woman goes through.

Any comments?
