Good day to everyone. This is my first post, I decided to sign in, because I can’t find answers to some question.
I’m thinking about treating low testosterone, of course. Which is why I’m posting here.
I have pretty much all ‘stereotypical’ symptoms.
There are only handful of doctors with decent idea in my country, so I would need to make quite a journey to reach one.
So before I go, I want to learn as much as I can.
Basically, what’s bugging me is free testosterone levels checking/diagnosis.
There are free testosterone tests around.
Most of them claim that average range is about 40 - 250 pg/ml or 4-25 ng/dl. Which makes it about 1%-4% of total testosterone, which is how it’s supposed to be.

However, some studies
like MMA fighter tests here
And
https://onlinelibrary.wiley.com/doi/pdf/10.1111/j.1442-2042.2005.01143.x
Show range of levels that are literally 10 times smaller.
From what I’ve seen, those are values which people on these boards are reporting as well.
Free T tests that I have available in Poland likewise show those small values as reference range. Like, 1 t- 28.2 pg/ml as reference ranges.
Are there some different methods that produce concentrations order of magnitude lower?
I’ve found something like this, and it seems there are some faulty methods out there, unfortunately.
Or are those references values just from old, ill men, and are out of whack?
I’m confused.
Thanks for any help.
