I've run tren before and been very capable of coping with any and all side effects. Unfortunately, in my current cycle, I am having serious trouble. I am running a very simple tren/test cycle (as I have done in the past) with 75mgED of tren and 800mg/week of test cyp. I've only been on for a week and the pain in my kidney region is making it impossible for me to work (I work construction which involves a lot of heavy lifting involving the lower back). I've run the same cycle in the past with excellent results and this side effect was onlya minor inconvenience, where as now it is debilitating. Anyway,does anyone know why this might happen, it's the same exact stuff I've used in the past. Also, would it make any sense to dilute the tren by 1/2 with Equipose, which I happen to have on hand? This would change my cycle to 800mg test cyp/wk along with approximately 37.5mg tren ED and 25 mg EQ ED? I'm also on 50mg of dbol for the first four weeks and have proper pct and am taking arimidex through the cycle. Thanks.
