ThermoLife International is now producing the first tribulus terrestris product to ever contain more than 20% protodioscin. This is important because protodioscin is the active ingredient in tribulus terretris that is responsible for stimulating the luteinizing hormone and raising testosterone levels (naturally). Most supplement companies just sell tribulus with no active ingredient. Heck, most companies do not even know what protodioscin is. To prove this, the good folks at Thermolife have commissioned analytical studies on 8 of the top selling products that contain tribulus terestris.

The results are a damming indictment of many of the fraudulent claims being made by some of the biggest companies in the unregulated industry of dietary supplements. Anybody who tries the new Tribosten will know the difference. ThermoLife International is the first and only company to ever release a tribulus terrestris based protodioscin product of this magnitude.

• Tribosten™ – Protodioscin Delivery System ™ has taken over as the worlds # 1 Tribulus terrestris product. ThermoLife International's research and development team has worked directly with the first and only American scientists to separate pure protodioscin from the Tribulus terrestris plant.
• Previously, this technology was only known to a handful of Bulgarian scientists who kept this secret under lock and key. This new technology has enabled ThermoLife International to produce Tribosten, a superior Tribulus terrestris product with a higher percentage of protodioscin than anything else ever available before. This is important because protodioscin is the active ingredient in Tribulus terrestris that is responsible for stimulating the Luteinizing Hormone and ultimately raising testosterone levels (naturally). This combined with Bioperine, a patented extract for increasing bio-availability of oral supplements guarantees you the finest Tribulus product your money can buy and the only Protodioscin Delivery System available.
