Hard to know how to advise you, given that I don't know much about your cycle history. I've only read through a few of your previous posts.
My focus is also on powerlifting, so I can tell you what I've preferred since I started. For strength gains, Test-only with an oral or 2 stacked on top can be pretty fucking fantastic. You can run test pretty high without running into major side effects, as long as you're running an AI with it. A gram of test is pretty great (I don't know what doses you've run before).
I also love dbol for the feeling. Halo, for short periods of time leading up to a meet, is without a doubt the best drug I've tried. It's insane. Epistane has been good to me as well, both for strength and a bit of body recomp. I get slightly leaner, and a bit more vascular when I run it. The results are pretty quick.
My next cycle will be Test and EQ. I've never run EQ before, so I can't speak directly to its effects, but I've been advise that it will be pretty great. Probably gonna run test at 500 and eq at 500 to start, and end up at a gram of test with it. And of course I'll run at least 1 oral for most of the cycle.
Just some thoughts.
