Need some opinions advice. Here is the backround of current cycle-

Started July 11:

-Test cyp 500mg/week (mon and thurs 250mg) finished that bottle and started Test Sust on Sept 15- taking 125mg EOD=close to 500mg/wk.
I am on an AI taking eod(extem) and also started clen a week ago-plan on 2 weeks on then 2 off. Not sure I will continue the clen again considering I cant sleep worth a shit (maybe 4-5 hours of sleep a day).

The question is that I only have a week left of the Sust and was considering changing back to Test E (this was my first test I took for 8 weeks from March to April) My plan is to do another 4-5 weeks of test but was wondering if switching to a different Test would make any difference or complications. Also would adding another steroid be beneficial since I am only going to be on for another 4-5 weeks, if so what do you recommend. I do have all my PCT in place (clomid, extem) except HCG. Should I look at getting some or since I am kind of a newbie is it important to have it. To be honest I am not sure what it does for you, tried researching but the info and lingo is to complicated for my dumb ass. I want the PCT to be as smooth as possible and to try to keep my gains. I went threw hell last time not taking PCT but now I have the info and learned from you fellas on this sight. Thanks for the help
