Its possible...... I will say that I have never tried any compound, hormonal or non, that I have not had any effects from (some effects are good and some bad).....but its possible I guess.That is quite interesting you are noticing no effects still outside of the general libido boost. Maybe you don't respond to bulbine... I get nothing from any tribulus product but I do from many other test boosting ingredients (even though trib technically does not boost test).
