Testosterone Free Calc

Free testosterone (approximately 2-3%) is the portion of testosterone that is not bound to any proteins in the blood and is “free” to enter the cells and exert biological effects. 33-54% percent is weakly bound to albumin (called BIOAVAILABLE), with the rest bound to SHBG (44-65%).
