Increasing T may help explain it. I'm on 120mg up from 100mg and when that changed I did jump a bit everywhere, but also are you on HCG or any other supplementals along with the T? (General Practitioner or Clinic)? Estrogen may have a hand in it with water retention. I got that then started taking Aromasin and now dropped it for Letrone daily to see how that plays out for me. So far so good. A mild AI would help maybe after you get your tests back.
What was the reason to go to 175? That may be close to the ceiling for TRT though I've seen some state they are on 300mg weekly. I'm pretty solid at 120mg weekly split SubQ.
Whatever caused water retention, if that's what it is, which is a good explanation, it would level out after a few weeks.
