So I was listening to a talk by Dr. Robert Carlson (heart surgeon) about TRT and the heart and he talked quite a bit about bioavailable T and why it's more important than Free T. Basically, from what I understood, bioavailable T is what you have after SHBG does its work, and free T doesn't take that into account. Is that correct? Is this an important marker to be tracking?
He uses this tool to calculate bioavailable T: http://www.issam.ch/freetesto.htm
I calculated mine using my last blood test and here are my results for bioavailable T: 688 ng/dL = 60.5 %
He mentioned in the video that he likes to see it from 400-600 and even higher in some cases, depending on the man. So, based on that, I'm sitting pretty good (which matches the way I feel, for sure).
