This implies that trenbolone leaves the body as beta-glucuronides or sulfates, which means mostly non metabolized. That is why you get a darker urine on trenbolone. It doesn't have anything to do with the kidneys.
you explained why it turns our piss dark ..now ill explain why it is hard on your kidneys ..tren is made up of three double bond molecules...in order for our body to dispose of this foreign substance these bonds needs to be broken down ...the kidneys play the major role in this process. Tren is not easily metabolized out of our system. Also it is believed additional strain in put on kidneys occurs by increased rate of protein synthesis. The first half of this is scientific fact ..the second part re protein synthesis is speculation.
