How much TRT are you taking? 200mg a week? How old are you? I don't know much about YK, but testosterone and age will have your PSA rise. The older you get the more careful you need to be. When I first started TRT probably 10 years or so ago, my PSA was around 1.3. Androgel had my PSA level rise to 2.2.-2.3 over the years. When I transitioned to 200mg a week injections my PSA rose steadily to 3.0. Had it checked by my urologist and he said I was fine, other than an enlarged prostate.
However, when I decided to hit a 12 week cycle my PSA went as high as 5.8. Had to get an MRI and specific blood test to determine possibility of tumors/cancer. MRI showed my prostate was inflamed and enlarged, but no tumors. However, it took probably 9-10 months for my PSA to return to 3.0.
When people do their bloodwork most are not checking their prostate. When you get older you have to, and if you're using steroids it will dramatically affect it. TRT will also affect your prostate.
