For me, I've decided that I'll only use tren leading up to a powerlifting meet, as a way to control weight for a few months while still gaining strength. I can gain more strength by just using test/orals, and I can eat more that way.
I'll also add in EQ next time I run tren, so I may have a different opinion after my next cycle. That could be something of a game changer.
About your bodyweight: I don't know shit about bodybuilding, specifically show prep during the last 72 hours or so before getting on stage, so what I have to say may not be remotely useful, but....
I have cut as much as about 15 lbs of water for a meet, without much trouble, and in the weight range we're talking about here. My last meet I went from mid 190's the day before weigh-in, to 180 weigh-in day, and back up to mid 190's by the end of that day. That sort of weight cut may not make sense for bodybuilding, but it might. I really don't know, just thought I'd let you know that it's easily do-able if it becomes necessary. You just have to start preparing for it a week out.
