hey guys, new member but have been checking this site out extensively for the past few years. I'm 37 and have completed 2 cycles (cyp only) over the past 14 months with moderately impressive results. I was preparing to start my next cycle of test only, thought about adding decca or dbol but not sure, I have a few weeks to make that decision. that is not the purpose of this question at this time. my question is that a friend of mine is now telling me that he just found heard (and he has been doing it longer than I have) that we should be switching our tests up as far as cycling with E, cyp, and sust. I have 2 cycles of cyp done as I said was going to start a 3rd in a few weeks. I had looked in the forum and didn't see anything that directly said this (I always double check my buddy on here. you guys rock!) not saying that he will steer me in the wrong direction, but I like you guys as sources. so in this whole thing is my question; should I switch my tests from cycle to cycle?
I know that E and cyp are very close to each other and almost interchangeable, sust I'm not too familiar with. but being so close, does it even matter to switch between the 2?
if you could help me out on this nagging question, and I know someone has an answer for me I would appreciate it. THANKS
