So as a backstory, ive never used steroids , but a while ago i was having some fatigue issues so i had my test. checked in a blood test.
However the doctor only checked on thing, and i have no idea what it was. He didnt give me any units of measurement, only that it was "18" and that it was lower than he would have expected (high 20s). He actually asked me if i had been taking any test supplements, which scared me cuz that is a pretty serious drop (due to negative feedback). Anyways this bummed me out and i want to get it checked again as i think maybe lack of sleep, lots of stress, and bad diet, as well as overtraining resulted in a lower level.

So i was wondering what i should get him to check this time, so that i can actually compare it with other people, or hopefully post the results on here where you guys can actually make sense of it.

I was going to check these things after reading another post on a different board about someone with hypgonadism or something.

Total testosterone (Ng/dl)

Free testosterone (pg/ml)

Sex hormone binding globulin (nmol/l)

Free testosterone percent (%)

Thanks for reading this.
