So, yeah obviously you need to move up several weightclasses, but there's no point in doing that now 3 weeks out from a meet, it's just going to be either fat or water weight and needlessly drop your wilks score, which you might not care about now, but you're going to want to look back on later in your lifting career to see how much farther you've truly come. You might as well just compete 165 at this point (I assume 165 is either a weightclass if not within a couple lbs of one in whatever fed you're competing in)
So you're plan is to load on creatine but not gain any weight... why? Creatine won't make your 1rm stronger, but it will increase work capacity -- which won't do much for you considering you're doing 9 singles at most on the day of the comp.
Why in all holy fuck would you hit numbers 10-40lbs higher in the gym than you plan on hitting in competition 2 weeks out? If you can hit those numbers, why not do it in competition? And if you can't hit those numbers, why would you fry your nerves attempting them this close to a meet? How does that benefit you?
1 week out you should be resting. Technique work with a bar at most. Especially if you plan on frying your nerves 2 weeks out, you're going to need all the rest you can get.
Not that it means much now, but 7% is about 2x as lean as you'll want to be for a powerlifting competition. Some guys can pull off lifting at sub 10% without it hurting their numbers, but w/e I guess you'll find out for yourself come competition day.
Look, I'm not trying to stress you out before your first meet because ultimately your first meet is just about getting the experience under your belt, but to be brutally honest nothing about your prep here makes a bit of sense.
