What's Free Testosterone?
Free T is testosterone that is present within the bloodstream or not bound (locked) to a chemical called albumin. But it's also the functional T, If we were to breakdown testosterone say like how we know estrogen is, i.e.. E1, E2, E3,
FT-(Free T) is about 2% the bioavailable part of testosterone that's
free to bind with androgen receptors. This is the same principle as to how free E2 with estrogen receptors.
BT-Bound T or 98%
-which is 38% albumin (bloodstream)
-SHBG is 60% (sex-hormone-binding-globulin)
The following post will talk about these levels and what they represent.
