I'm sorry for being abrupt. The only other time I had any kidney issue was using ibuprofin about 6 months ago. I stopped using it when I got kidney soreness.
I stuck with 25mg/day until soreness (about 7 days), then went to 25 eod, then every third (where I am now).
I have no familial history of kidney problems. I do have post pubertal hypogonadism and have since I was 31 yo. My test levels dropped through the floor (high 200's range) then, and I haven't felt healthy since.
I am 48 yo. I have been an active bodybuilder for most of my adult life, on and off but mostly on. I haven't been an AAS user except for two short cycles of test I did back in the 1980's (full recovery post-cycle).
