Zinc is essential for the increased amount of testosterone in the human body. Oysters contain 10 times the zinc there is found in beef steak. Also, the oyster has 59 trace elements that the body needs which includes vitamins, taurine, amino acids, omega 3 and 6 fish oils. The oyster extract in Testofuel will naturally and safely boost the testosterone levels of its users, keep the estrogen low and avoid “man boobs”, and decrease the chances of being overtrained. Your progressive protein synthesis ensures you have the muscles. Zinc is needed for ribozyme (RNA) reaction. RNA is a well known molecule, which is capable of accelerating certain biochemical reactions similar to action taken by protein enzymes.
Quercetin has been studied in basic research and small clinical trials .    While quercetin supplements have been promoted for the treatment of cancer and various other diseases,  there is no evidence that quercetin (via supplements or in food) is useful to treat cancer  or any disease.   The US FDA has issued warning letters to emphasize that quercetin is neither a defined nutrient nor an antioxidant, cannot be assigned a dietary content level , and is not regulated as a drug to treat any human disease.  
Cybergenics 6 week program is the best weight loss program I’ve ever used. I’ve used it twice. Once in 1997 and again in 2009; both times to loose weight, 45 lb & 43 lb weight loss respectively. It worked well and helped me meet my weight loss goals, especially after I had platued at a body weight I could not seemingly get down past. This system really works. I’m glad they still sell it. I originally found it in Muscule & Fitness. Because it worked so well in 1997, I bought a 2nd box, and held onto it. Then last year, I used that 2nd box. It was 12 yrs old, but it still worked just as good as before. Simply Amazing. I hope the current stuff is as good as the original stuff.
