The ingredient 7-Methoxyflavone is the reason why. I researched this ingredient through several medical testing journals and this one item is the key to my testosterone levels increasing as high as they have. Another interesting fact is that I'm 61 years of age and I've been weightlifting for over 40 years. With this one product alone, I continually have acne break-outs and this is always a sure sign that your testosterone levels are elevated! Also, I've been tested through an independent testing lab in Minnesota and my "test" levels were 1,000% ABOVE where they are without this product! THIS ITEM IS ABSOLUTELY THE REAL DEAL!
