How long have you been on trt? Once your levels stabilize, that should go away.
If you been on a while, try doing 2 shots of 100 each on mon /Thurs to help keep it level.
Could be a soap/shampoo issue, or hygiene if you sweat a ton, etc.
Did you just start TRT? or have you been on a while? The acne is often due to the change in test and sometimes E levels, once you have been on for a while it often subsides. That being said 200MG is usually on the high end for TRT, usually only get that kind of dose from a clinic and not a gen prac doc or endo and its iften just to get you hooked, invariably they cut the dose back on you after some time.
Its normal. I broke out some when I first started but it settled down after a few months(hardly any now). Now the increase in back hair? That still grows like weeds! LMAO
