Yeah it leans you out like crazy. Not a placebo. It is a creatin&Nitic Oxide compound. Mine is red fruit punch. In the cardio area, I can run in the top 10 intestity for and hour where 40 mins was my max and I was done. now I run for an hour and then do 20 mins on the ski machine. In the work out area its insane. There has been a 30% across the board in lifting. Im telling you guys, its crazy awsome. The endurace factor alone is worth the 30 bucks.
