yeah it is a lemon like flavor a bit harsh but trust me it is in my opinion the best pre-workout drink so i get over the flavor real fast. I have even thrown some green mag in with the flood to dull the taste not sure if is a good way to use the green mag but it makes it taste actually pretty good. i only use the fllood on training days and the green mag everyday. On training days i usually take the green mag morning and night and once a day on non training days. not sure if that is good protocol for the product but it seems to be working well for me the last three weeks.
