 During the search for new anabolics in the 1970's, researchers strived to develop a compound that didn't have the pharmaceutical steroid status. The patent for methoxyflavone was first filed in 1977 by Chinoin, a Hungarian pharmaceutical company and leader in flavonoid research and knowledge. Then, in the 1980's, livestock producers introduced it as a new compound to increase lean mass in animals. Now, some 20 years later, with the end of its patent protection (which means anyone can copy the product, which is easy, since patents have to list exact manufacturing techniques), a new supplement, called methoxyisoflavone, popped onto the performance-supplement market... with no real science to back its claims.Unfortunately, patents don't mean a product works. They just mean the product is patented. In addition, methoxyflavones appear to have negative effects on important testosterone-conversion enzymes, whereby it inhibits the enzyme responsible for converting precursor hormones into testosterone. And, due to its similar structure to ipriflavone, it may even enhance the effects of estrogen in certain parts of the body (which isn't in the least bit beneficial for men trying to put on muscle mass).

 5-Methyl-7-methoxyisoflavone (CAS NO.82517-12-2) is used for sports and fitness support (Enhancing Performance) and it is a chemical derivative of Ipriflavone, but it is marketed as a bodybuilding aid.
