Hi People,
My Total Testosterone dropped from 19 nmol/l to 14 nmol/l, from age 19 to 20, is it normal?
I read in medical journals that usually a man's Testosterone levels peak in his late 20`s, and start to drop only after 30`s usually 1% per year.
But is it normal what is happening to me...
Felt bad for the last couple of years. God hormone tests done.
I constantly feel cold +Tired and have yellowish dry skin.
Feel like Death ( A shadow of my former self) SRS. The change occurred suddenly as if someone turned a switch. Im 21 btw.
