More research still haha!
A lot of the herbal supps linked with increasing total testosterone seem to do absolutely shit all... trib and the such included.
What I am trying to achieve is a herbal stack that will keep things right at the high end of normal.
Chrysin and other herbal based anti est's are likely to be useless at this test range also - although they wouldnt hurt.
The priority seems to fall on inhibiting SHBG-testosterone binding. Nettle root, Avena Sativa are two that have been suggested to do this - any more?
