Tribulus Terrestris

In the search for natural testosterone enhancers, Tribulus terrestris is shown to be a key catalyst for the production of luteinizing hormone (LH) in the body, which in turn, helps to significantly raise testosterone levels. This mechanism of testosterone release by Tribulus terrestris is due to the natural presence of biologically active saponins, especially protodioscin. Bodybuilders should always look for products that contain a high, standardized content of protodioscin (minimum 40%) and total saponins (60%) for optimum effectiveness. Increase your mass gain potential among other key benefits with Tribulus-based supplements.

    PROSOURCEANDROTESTTrue Clinical Grade Test Boosting Power Natural, Clinically Tested Active Ingredient Matrix Ultra Bioactive Testosterone Enhancement Power Full Spectrum, Protodioscin-Rich Super Compound Up to a 217% Increase in Free Testosterone Up to a 275% Increase in Total Testosterone With AndroTest®, the ProSource research and development team has ushered in a new modern era of T-boosting science. What separates AndroTest from virtually every other T-booster out there is its superior degree of standardization and unrivaled potency. AndroTest’s key ingredient, a full-spectrum protodioscin-rich botanical super-compound, is synthesized via a painstaking refinement method that can include up to 20 separate extractions. The result is the first T-booster ever standardized for a minimum of 40% bioactive protodioscin levels. Research has established that protodioscin is a key catalyst responsible for helping to enhance the production of luteinizing hormone (LH), which in turn, helps raise testosterone levels in the body. Many bodybuilding experts consider this to be the ideal mechanism for raising test levels because it works by stimulating the natural production of the body’s own testosterone rather than relying on the artificial replacement of it as is the case with synthetic testosterone drugs.What’s more, this superior-grade driver of testosterone support is also standardized for a minimum of 60% furastanol saponins and 80% total saponins content, yielding the most potent and complete spectrum of active T-boosting components in existence. Given this due diligence in standardization and manufacturing protocols, it should come as no surprise that AndroTest has made headlines in the realm of independent clinical research.In a randomized, placebo-controlled, double blind clinical study, AndroTest produced statistically significant increases in total testosterone levels, averaging 59.88% over baseline, with some subjects showing total increases as high as 275% over baseline. And major increases in free testosterone, averaging 59.75% over baseline, with some subjects reaching up to 218% over baseline. This means that some subjects using AndroTest experienced nearly a three-fold increase in testosterone levels. Equally impressive is the fact that the increased testosterone levels (after two weeks use) were observed throughout the measurement points of the study, which is especially important since sustained increases in testosterone are the key to enhancing muscle growth.When it comes to driving natural T-level increases that serve as the solid foundation for optimum performance, there’s simply no viable alternative than the one and only, clinical strength AndroTest.   *Not Available In California More about AndroTest: Get the Alpha Male Advantage Man Up!

    PROSOURCETRIBUTESTPotent Tribulus terrestris extract for high-quality T-boosting power 1000 Mg High-Grade Bulgarian Tribulus Terrestri Highest Potency In Its Price Range Standardized for 40% Total Saponins Ultra-Pure Quality Extract When searching for a quality T-booster at an economical price it is highly recommended that it be an extract of Tribulus terrestris from Bulgaria, and, that it be a ProSource product to ensure optimum quality and efficacy. This is particularly important since there is such a wide disparity that exists among supplements in this category. Fortunately, ProSource TribuTest takes the guesswork out of the equation by providing a powerful and ultra-pure product that supplies 1000 mg of genuine Bulgarian Tribulus extract. Tribulus from Bulgaria has been documented to yield significantly higher potencies and powerful saponins not found in tribulus from other parts of the world. TribuTest is specially processed to yield a highly bioactive standardized extract (40% minimum steroidal saponins). The only tribulus products we've seen that offer higher value are the AndroTest formulations, which dominate this category, and for very good reason. For those athletes on a tighter budget, however, TribuTest is a potent and praiseworthy alternative.

    This extract of Tribulus terrestris (aerial parts and fruits) contains 1000 mg per serving, standardized for 45% total saponins, with no documented content of protodioscin. Protodioscin (from Tribulus extracts with adequate content, usually standardized to 35% or more) has been linked to increased levels of lutenizing hormone (LH) in athletes, with consequent enhancement of blood testosterone levels.
