No, I'm not fat. I used to be a subhuman during my puberty when I was fat, but nowadays at age of 23, I'm fit and have low body fat percentage that continues to drop; it will be dropping until it reaches a single-digit number. Currently, it's about 11%, I guess.
Also, I don't have low T symptoms such as erectile dysfunction, depression, constant tiredness, etc..., but I have other reasons to still think I have low T.
Using the mirror won't help, because my body doesn't display signs of low T, which doesn't mean I don't have low T.
So, are there other hormones whose values have to be checked.
