Wow who wrote that? That's in direct contrast to everything I have. There is a whole book written about workout nutrition (pre, during and post) called Nutrient Timing. Great book with quoting lots of research on Workout nutrition. The rest of the nutrition advice in there pretty much sucks.
ANYWAY, I believe they quote studies that show gains as much as 300% more protein synthesis if post-workout drink is consumed immediately after versus several hours or so. And fat burn is considerably greater too.
I'd recommend mixing up a 2 scoop serving of Surge and drink 1/3 before, 1/3 during and 1/3 after. I have my male clients use 3 scoops. The results are pretty amazing.
