Your Free T while in range doesn’t necessarily mean you are fine and dandy, when my Free T was 15.0 I had full blown low T symptoms that didn’t disappear until Free T was at the top of the ranges. There are 2 percent of the population well above these reference ranges and if you are one of those men, you need more Free T than average male to be normal, normal for “you”.
These normal ranges are used by insurance companies to deny treatment, in reality testosterone levels have been declining over the decades and if you are going to lie down and accept it, then your quality of life will be lower.
Last year the ranges were decreased (348-1198 to 264-916) and in 20 more years it will happen again. Your Free T is in a range that would give most men symptoms of low T ot at least the feeling that something is off. Your Free T is far from optimal, those on TRT being treated by competent doctors see symptoms vanish in the 20-25 ranges according to my private hormone specialists who has treated more than 10,000 patients.
Suggest your SHBG is midrange or higher contributing to sub-optimal Free T.
