Been in the gym 35+ years and am 51 (if any of that helps).I am about to start my second ever cycle. My first was using MSTEN ( 2, 17a-dimethyl-5aandrosta-1-en-17B-ol-3-one). I was about to stack MSTEN with Halodrol this time around . However, I decided to have my personal physician test my testosterone and it was very low! He prescribed Andro-Gel 1.62 and I just staring using it this past week. Since I am using something "new" to my body I thought it was too soon to stack so I was going to focus just on the MSTEN this time around. Anyone have any experience/feedback cycling pro-hormone and prescription test. Anything I should be concerned about or do "differently"? I am being told that, since I am starting and using real test, that I should use a SERM during my PCT. I didn't use it before (MSTEN is supposedly not a vey "harsh" pro-hormone). Any help or feedback would be appreciated.
