correct!!
but if men who dont get thier levels checked early on,say in thier 30's to 40's and never have or had them checked,IMO you will eventually havet to go on trt,and im speaking from experience,and i never done AAS until i was on trt,so that part is out,it didnt cause me to be a testosterone replacement therapy (TRT) person,its just over the years my levels just decreased and eventually hit rock bottom
my advice to anyone around age 33 to 35 start getting thier levels checked to save yourself problems when you get older,im 45 nearly 46 and i wish i had off done it years before
