Pulled form one of the Magazines I get on a monthly basis, um... just for the articles.
" ERYTHROPOIETIN ( EOP ) boost athletic performance and remember where you parked" EPO stimulates the production of red blood cells. The more red blood cells you have at a given time ( I.E. Lance Armstrong - during the tour de france) the more oxygen your blood can carry, the better your muscles perform. Scientists have noticed a side effect, it enhances memory.
Good Luck!
