Proven Tribulus that works

Not Tribulus terrestris, but Tribulus alatus (over 600mg in T-Anabol)

Tribulus alatus is a plant that grows in the Sahara and Middle East. It is a relative of Tribulus terrestris, well known in the sports world in the form of supplements which manufacturers claim raise testosterone levels. Recent studies have put paid to these claims, but according to Egyptian researchers, T. alatus is a different kettle of fish.

The Egyptians did tests on male rats. The animals were given extracts of Tribulus alatus through a tube into the stomach every day for a period of forty days. Afterwards the researchers measured the amount of free testosterone in the rats’ blood.
