This is because of a compound called Sex Hormone Binding Globulin (SHBG) which binds the majority of the Total Testosterone in your body and lowers your “Free T” levels…
Think of the bound Total Testosterone as the casualties, because binding this hormone inhibits its function within the body...
Which is why if you want to get that killer instinct back, enjoy 'bigger loads', have increased confidence, and a
sexier-looking physique, you need to increase your “Free Testosterone” levels (the survivors)…
