For almost all of my cycling, I use a good amount of test and add other compounds on top of it. Tren is no exception. I start tren low and build to a moderate dose. It's only in the final wks of a prep that I ever run a dose that is considered high. I've never run low test with tren. I know there are guys saying it's great and it is kind of popular now. Personally, I know my body and I know how harsh tren is. IMO, it's best to use tren to supplement the cycle, not to base the cycle around it. I see other compounds as a way to push the cycle that much further, into my desired direction. It doesn't take a lot of tren to add to hardness/leaness and even gain some muscle, if the diet allows. Test will always be my base and do the "heavy lifting" in my program. Then tren, or deca, or whatever else.
