Cool, your diet sounds similar to mine - I do a lot of eggs and rotate between salmon and steak
Adding carbs just smooths me out - I recently started throwing in 100g of carbs and all the life long crappy side effects I had pre keto came roaring back:
-I'm getting fat and holding water like a motherfucker. I hope this settles down, but in hindsight I always held water in the past when even on a low dose of test.
-The small skin rash I'd had my entire adult life is now making a return with carbs.
-I'd forgotten about digestive distress that I'd experienced my whole life on even moderate carbs. Taking a crap each morning was quick and pleasant on keto. Now it's back to its old former self.
Overall I feel like shit and really don't want to ride it out.. my bloodwork on keto was absolutely stellar, and I'm guessing it's going to go back to being sub standard soon, though only time will tell.
I don't feel any more pumped with 100 carbs than I did on keto - and I know from past experience that 100g works for my body. At the age of 41 on TRT/Keto I actually feel better than I did at 24 on more gear and moderate carbs. This is just my experience though.
For some reason moderate sized junk refeeds don't seem to bring out any of the negatives. I went a long time without refeeds, but suspect I'd be happier doing them than 'doing carbs' again
