Frustanol Saponins include a VARIETY of saponins OTHER than PROTODIOSCIN--which is the ACTIVE steroidal saponin responsible for stimulating the production of LH. 90% Protod. would be GREAT. But that is not the claim. Be very careful when it comes to the standardization of Tribulus Terrestris.

The ONLY Tribulus supplements that work are: Tribex, tribestan, Vitrix, Endotest, and Fuzu. Stick with those; you will be very pleased with the test surge these can give. ALSO--Tongkat Ali (Eurycoma Longfolia) is also a great herb that has been clinically proven to increase testosterone levels in humans. Use REDKAT. Good SHiot.
