Back when i was traveling india, being stressed, STRESSED, i started feeling tired/depressed and all sort of shit.
Did bloods
Free testosterone (8-50) mine was 10
TT (240-830) mine was 260
Estrogene was above 35, mine was 40.
Came back home, recovered, startet eating good, alittle workout, worked with the stress and about a month after my totalt testosterone was 600..... So if u dont know if you are primary or secondary, give it a try................
