I've been on doctor prescribed TRT for a year. 160mg test cyp a week (80mg each on Sunday and Thursday). I had my quarterly blood test at quest, and out of curiosity, drew a Rythm sample in the parking lot immediately on leaving. This is about as close a timeframe as I could possibly get. I know people have mentioned a lot of companies that you can third-party order tests and get the draw done at quest, but that is NOT available as an option in my area. So, I was hoping Rythm might be of use for some of the tests they run, but these results give me pause. (Rythm tests much more than this, I.e. cholesterol, liver function, etc, but these are the four tests that overlapped for my specific blood work I get done). I may end up paying for the larger array at quest to do a side by side of everything.
