For the past 15 years my creatinine has been high. Usually the lab cut off is 1.33, and mine is over, up to 1.46. All other kidney labs (BUN) are normal. I have had 4 ultrasounds, all normal. I ve been to two kidney doctors and a Urologist. Found no causes. I ve had several urine tests, 24 hour collections. Always normal. No protein in urine. I take 200 mg testosterone cypinate every 10 days due to peaks and very bad valleys. One of the kidney docs said “there are no testosterone receptors in the kidneys” so that’s not the cause. He believes from working out and breaking down muscle is the issue and said don’t worry about it. Anyone have an opinion on could TRT be hurting my kidneys? Thank you.
