5 Methyl 7 methoxyisoflavone

5-Methyl-7-methoxyisoflavone, commonly referred to simply as methoxyisoflavone, is a chemical compound marketed as a bodybuilding supplement. However, there is very little clinical evidence to support its usefulness. A study published in 2006 examined the effect of methoxyflavone on training adaptations and markers of muscle anabolism and catabolism. No measurable effects were observed in athletic performance or in levels of testosterone and cortisol.
