Over 4,000 companies worldwide are selling Bulgarian Tribulus right now, but the number of companies that really know how to make Bulgarian Tribulus can be counted with the number of fingers on one hand. The best known manufacturers are T Boost of Bulgaria who make TTT and Staminaxe and Sopharma who make Tribestan!
There are limited resources of Bulgarian tribulus in the country of Bulgaria. The climate in this country is perfect for growing tribulus crops which are carefully harvested only a few timeas a year. The market is now flooded with manufacturers of Indian and Chinese products which do not have the same pharmacological and physiological properties as the Bulgarian Tribulus terrestris extract and many are totally not effective!
Over recent years the consumer has been confused with various brands offering protodioscin content between 50% and 90%. The consumer automatically gets attracted to these high percentages but does not understand the ingredients.
The truth is there are various active ingredients in Bulgarian Tribulus called saponins. Saponins contain only a handful of active ingredients. Included in these Saponins are protodioscin and protogracillin together with other key active ingredients, protodioscin being the main active ingredient.
Many companies do not differentiate between saponins and protodioscin. The level of protodioscin can not go over 45%, but saponins can. In order for companies to sell more of their products they write 80%-90%of protodioscin but what is advertised is the percentage of saponins. You will have noticed that many tribulus products have been took of the world market since 2011 due to these false claims!
The product Tribestan® for example contains at least 45% of standardized saponins (from the shoot of the plant). The true superiority of the effectiveness of Tribestan® is expressed biologically where are present Protodioscin, Protogracillin (the key active ingredients), and other key saponins in critically important ratios offering dramatic results! TTT and Staminaxe also contain around 40% saponins and are very effective.
