I am a 47 male. about 10-15 years ago I had my test level checked and it was low 300's, don't remember the number exactly. the doc told me this was within the normal range and thought no more of it. fast forward to today and I figured I should have it checked again so I went to a new dr and explained that I tested low several years ago and I have all the symptoms of low test (low libido, fatigue, not able to build muscle etc). he said they like it to be 600-800 range so he took some blood and the results are 366 for total test. I'm hoping that this is low enough for him to prescribe test, still waiting to hear back from him.
