So your next lift is Friday I'm guessing, which means you get Sat/Sun to rest. I think yes, make the attempt at 175 all the way across. Set your mind on finishing every rep. Let your body fail if it must, but not your mind. Then, if you have to lay a rep on the safeties, you've gained needed data, and have two days to "sleep it off" or whatever.
Any gain's good gain at this stage. 2lb/wk, 4lb/wk. It's going to be a mix of muscle/fat. But it is very very short term. Aim for a 25lb net gain to start and hit the food/barbell as hard as you need to to make it happen, and then reassess. Punctuated equilibrium: Gain, stabilize, gain, stabilize.
If you're trying to eat clean, don't. When Tim packed on pounds, he'd hit as much milk as possible (even an occasional GOMAD; usually for a couple days here and there as I don't think it's sustainable unless your belly is made of Teflon), bowls of sugary cereal with lots of milk, as much slab-meat and ground-meat as he could get his wife to cook him ... AND THEN he'd show up to our evening Bible Study with a bag of discount Whoppers from Burger King and methodically plow through three of them during the lesson and wash it down with full-sugared soda.
When I gained 40lbs, I think 20lbs was on the pure LP phase, and the other 20 came over an additional ...6? months? But I ate all the things, and even made a game of it, finding as many one-off cheeseburger joints as I could, eating their biggest thing, and buying a t-shirt. I was traveling through Western WA at the time and I still think of it as the "Great Cheeseburger Tour."
If the eating bit is painful, I think that's a good sign: For me it meant that it was easy to scale it back and STAY at 225 once I got there, been there +/-5lbs since 2019 not counting immediately after a surgery I had in 2021. Eating should legit be an additional daily workout right now, and should feel like cardio. If you're not sweating while you eat, something's wrong, lol. Ain't gonna give yourself the DIABEETUS in 8-16 weeks mate.
