Libido isn't just about testosterone. Test is just a piece of the puzzle.
Boron reportedly can improve D as noted and T possibly by impacting shbg.
DHEA can but it can also increase E2. Your body will decide where it shunts exogenous dhea so you may get the desired effect or you may not.
Fenugreek can increase T by virtue of impeding the 5-AR enzyme that turns T into DHT. Thus "a little" more T.
DIM-minimal effect but yes.
Tribulus - no clue where that number came from but most studies I've read show virtually no increase in T levels.

To answer your question "what's it doing to my body"? Answer is nothing other than wasting your money. Stick to optimizing your Vit D and low dose daily cialis. If issued continue pull full BW and go from there. imho.
