I'm a serious competitor, who in the last 4 yrs have been sidelined for about 3 yrs altogether with various injuries off and on. Most recent injury was groin injury that lasted 11 months, after I was back for 1 month I pulled my other groin that has been hurting for 9 months now. I also hurt my lower back lifting about 4 months ago that's still terrible. I've been told a 6 wk cycle of deca would cure me, is this true & what are the possible long term side effects,if this can totally cure me. Thanks in advance!
