I'm new to taking steroids and I'm trying to do my homework before I start. I am going to be running a test pro 250 and I want to run tren ace with it. I'm not sure how many IU to take. Before I have done 1 IU of test and .5 IU OF TREN in the same injectio once daily every day in the A.M. I'm 6'1" 200lbs and have about a 23% body fat. My goal is not to bulk but to lean up and stay around the 185lb mark. I've been told to run Nolvadex as my PCT. like I said I'm new and I don't know a lot about the PCT and what to really do on the off cycle. Any information and help would be greatly appreciated.
