In a remarkable turn of events, arguably one of the strangest in the history of athletic performance, an offshoot of research directed to help victims of muscle atrophy has now become an underground cult phenomenon among bodybuilders, world-class athletes and, strangely enough, couch potatoes from the "boomer" generation. Both professional athletes and weekend warriors are buying so much Endothil-CR (especially after the ban on steroids and steroid precursors) that finding a box has become just about impossible. Has everyone gone crazy? Well... not really.
