Tribestan (Tribulus Terrestris L.) is the original Tribulus Terrestris L. natural product. Developed in the 1970s and 1980s after 16 years of research by many scientists at the Chemical Pharmaceutical Research Institute in Sofia, Bulgaria. The research expanded on the herb and herbal species, creating a proprietary technology and methodologies to extract the valuable components of a wild herb. Further R&D efforts included incorporation in a tablet form of a substance greatly affected by absorbed humidity. Tribestan was approved for production and implemented in mainstream practice in 1985, and on the market ever since. The product is practically non-toxic and has no side effects - no changes of lifestyle required when accepting Tribestan. Tribestan is natural and safe. Tribestan is based on a proprietary extract from Sopharma and the active substance does not contain herbal particles.
