@Jocbro Nah there's different labs. Free-T's reference range is 4.5-25 ng/dL. Total T is the larger 249-836 ng/dL reference range (which may be age dependent) that I think you're mixing up with that 700-800 range.
And then there's the percentage free, which is a 1.1% to 3% reference range.
Lastly there's bioavailable T, which has a reference range of 108-500 ng/dL.
While not a T metric on it's own, it is related... Sex Hormone Biding Globulin. Its reference range, which again could be age specific, is 16.6-55.9 nmol/L.
These are right out of my labs from Quest Diagnostic that were used to figure out my hormone optimization protocol. Instead of being average we're aiming to get my totals to where I was when I was 19. I'm already seeing an improvement and the body fat is coming off.
@Aging-Chad I've heard lots of good stuff about Thorne products. I've got a bunch of their stuff in the mail and should be here in the next week or 2. Hit me up in a month if you're interested in if I see a difference.
As for TRT, @Apollo that 700-800 range is about where guys should aim for, but one thing I've learned is you really don't need to focuse on that total and should be more keen on what the free-T figure it at.
