Free Testosterone - What Is a Normal Value?


Hi guys.
I’ve seen in Internet that the avg free testosterone is about 12.
For a 35 y old Malé what is a low free test?
My value is 10.9 and total of 370.
Some say that free t is what counts and total t is irrelevant. Some endos say free t is not acurate!
Any thoughts on this ?


Numbers are irrelevant without the lab reference ranges printed on the bloodwork.


10.9 (8.8 - 27)


Well, that’s on the low end of the range. It’s not great.

Why don’t you go through the standard list of questions and we’ll see what we can come up with…

-describe body and facial hair
-describe where you carry fat and how changed
-health conditions, symptoms [history]
-Rx and OTC drugs, any hair loss drugs or prostate drugs ever
– real dangers! see this http://propeciahelp.com/overview49

  • lab results with ranges
    -describe diet [some create substantial damage with starvation diets]
    -describe training [some ruin there hormones by over training]
    -testes ache, ever, with a fever?
    -how have morning wood and nocturnal erections changed


One year ago test 560 free test 8

Chest fat , gyno
No libido, no morning wood
AS induced
I’ve got my history posted


Lh is the same free test a bit higher
Lower total test

Please link to your history. Consider in the future adding new questions to your original thread with your history so all of it is right there for those who take time to answer.

If your LH / FSH is up around 10 or higher (assuming normal ranges, etc) that’s an indicator that you are primary hypogonadism. I’d like to see the full history (with actual numbers and ranges) before making a judgement though.


E2 is as important as the T numbers. Some men here aren’t even on TRT but have high E2, which affected their quality of life, so they came here to learn how to manage E2.
