Due to the fact that many of these prohormones have a short half-life, ALRI has developed a proprietary delivery system called ProAbsorb-Rx TM. This delivery system is the only oral testosterone boosting formulation using this superior technology. This technology allows the tablet to deliver prohormones and testosterone to the systemic circulation by the intestinal lymphatic route, thereby circumventing first-pass inactivation in the liver. ProAbsorb-Rx TM dramatically increases bioavailability via lymphatic absorption and represents ALRI’s proprietary method used to prepare Metanabol®. ALRI’s tablets begin with natural hormones derived from yam sources into natural hormones. Natural hormones are identical to what your body produces. ProAbsorb-Rx TM is truly the first delivery system based upon true science dealing with hormones and not other types of compounds that does not translate when applied to hormonal products.
