Tribulus terrestris is an herb that has been in the spotlight for many years, and with good reason. However, you may be surprised to learn that the material used by the vast majority of sports nutrition companies is cheap, inert Asian material made from the berries of the plant, which is entirely the wrong part to use when sourcing the active ingredients. This is because only the berries play a part in traditional oriental medicine. Although Bulgarian Tribulus extract is made from the correct parts of the plant, the shoots, statistics on its active components have been dramatically over-exaggerated, having been based on outdated UV analysis. CNP Professional's material represents the Gold Standard of Tribulus terrestris shoot extracts, developed by a large German phytochemical company over several years and standardized for protodioscine content approximately 300% higher than Bulgarian material, as determined by modern HPLC analysis. This high spec analysis is also employed in the anti-doping protocols that govern Olympic athletes. In fact, CNP Professional Tribulus terrestris extract has been demonstrated not only to contain a high yield of protodioscine, but also the full array of tibuluo-saponins, -essential for their synergy in producing the effects associated with this closely guarded secret of eastern bloc athletes.
