I went to the doctor last week because I've been feeling tired/drowsy/depressed for about as long as I can remember. I'm 28, about 6 ft tall, 185 lbs, athletic build. He ordered a blood test.
The blood test came back that, on top of having extremely low testosterone, my kidney values were all over the place. My creatinine number showed as 7.4 (normal is apparently less than 1.9). My EFGR score came in at 4.
I have been consuming a rather high amount of protein due to trying to build muscle, and I also supplement creatine. Could that be enough to cause those values or do you think I have something to worry about.
