Fadogia Agrestis 20:1 (as FadogiaPure•) is the most potent Fadogia extract on the market. Fadogia has been shown to increase levels of testosterone in blood with 5 days of oral administration! Fadogia Agrestis increases total and free testosterone levels, as well as helping athletes recover from strenuous exercise. Studies suggest that it boosts testosterone and acts as a libido enhancer. In recent years Fadogia has become popular as a supplement for supporting Testosterone levels in men, where it works by mimicking the luteinizing hormones which the body uses as a signal to produce more Testosterone. In addition, Fadogia Agrestis is often used by athletes to improve performance. FadogiaPure• also works by decreasing the amount of sex-hormone binding globulin (SHBG) in the blood. SHBG is a type of protein that binds to sex hormones, predominantly testosterone and estrogen. When SHBG is bound to these proteins they cannot enter the cell and exert their effects. Hi-Tech's FadogiaPure• 20:1 extract contains many other beneficial compounds which help with this effect such as saponins, anthraquinones, flavonoids, and alkylamide glycosides that are not found in many other fadogia products.
