i have been working out for the past six years and i started my first cycle three weeks ago the gains are amazing so far. im up 10 pounds. im running 35mg of dbol,500mg of test e and 300 mg of deca a week. my question, ever since week two my lower back has been tighting up on me so bad during my lifts its killing me i cant even bend over or drive my car home. is this from the juice or from something else.oh yeah i have never had this promblem before. anyone have any ideas?
