Yep, whey is what you want. The second ingredient in Surge Recovery is whey (the first ingredient is glucose).
The biggest benefit that Surge has over Grow! Whey, though, is that it's already combined with the right kinds of carbs in the right amounts. So in terms of "bang for your buck" post-workout supplements, Surge is the best tool for the job, Grow! Whey would be second place.
(For discussion's sake, Metabolic Drive would be a distant third, since that protein formula is designed to be absorbed/digested slowly - not something you want immediately post-workout.)
