tribulus for test boosting eh....
Testafuranol™ is simply a trademarked name for the extracted compound Tribulus alatus
the literature claims it contains a high concentration of the active component Beta-Sitosterol as well as furastonolic saponins..
there are a couple of companies utilizing alatus, and I am not aware of any feedback from anyone regarding any notable effect on test boost, either on its own merit or in comparison to terrestris species
if you are in search of test boosting, there are many many things more worthwhile than this for you to look at
