Universal Nutrition Animal M-Stak is built on a foundation of natural anabolic flavones born from Eastern European athletic studies. These special flavones have long been theorized to help enhance targeted gains in lean muscle mass.
M-Stak combines the most powerful of these compounds in significant dosages, making the long storied potential of the product all the greater. Primary among these flavones are Beta-Ecdysterone (Cyanotis Vaga) and 5-Methyl-y-Methoxyisoflavone. These ingredients have the ability to shuttle nutrients specifically towards lean mass accumulation, a process known as 'nutrient partitioning.'
