I started using test-e about a year ago. Did a 14 week cycle of that and loved the improvements that I saw. After that I went to my doctor and was prescribed test-cyp which I have been on for about 8 months now. Currently I am cruising taking a 1/2 cc every other week and have been doing so for several months. When in a cycle I take 1cc twice a week. I'm looking for something to stack with the test-cyp that will both help me gain and lean out. I tried adding deca (1cc a week) to my first cycle and had good results with building but not so much leaning out. A friend suggested I try Tren (1cc a week) which I did for the following cycle. I saw good results initially but develop excruciating joint pain and had to stop using it. I want to begin another cycle around the first of the year but not sure what to get. My friend suggested masteron but seeing your video has made me think it's not the best idea. I don't know my exact body fat but I know I'm over 10%. My guess would be in the high teens. I don't know if it's necessary but let me give you background on me. I'll be 39 years old in February and in the military. Yes, I do want to continue to build but my main thing is, I want to keep my job. I've been in the military since 1997 and the nearly 20 years has put my body through hell. I need the strength and speed to keep up with the younger troops and keep my pain in check. I'm not doing any contests or shows. I just want to better myself and maintain the quality of life that I have and not succumb to my injuries from my years of military service. With that said, what do you suggest? I want to continue to gain muscle mass and lose the fat around my midsection.
