People read WAY too much into single studies; besides I think David Barr covered it well with his response.
I'll tell you my personal experience with Surge. I only recently began using it. Previously I had thought that a whey protein shake and some maltodextrin was good enough for post workout nutrition. I honestly thought that Surge was somewhat hyped. Sure, It might make a slight difference, but not enough to justify the expense.
Well, since I've been using Surge I really feel like I've found the "missing link" in my nutrition program. Surge gives me great sustained energy and strength during my workouts. My recovery has been MUCH improved--I can't overstate this benefit. I find myself recovered, energetic, and ready to workout again in record time. I'd say it's true that Surge will speed up your recovery from workouts by a full day.
Furthermore, in the last several weeks that I've been using Surge (1 scoop 15 min. before workout; 2 scoops, 1/2 hour after workout; 2 scoops, 1 hour later) I've put on some nice muscle--all while dieting! That's another huge benefit of Surge: used around my workouts, even while dieting, it has not lead to fat gain. It seems as if my body just absorbs the nutrients in Surge like a sponge--I believe it's very effeciently used by the body.
In fact, I've lost 50 lbs. over the last 10 months, and some of my best workouts and results have come since I've been using Surge.
I'm now completely sold on Surge and will never train without it--bulking, cutting, it doesn't matter. I'll simply consume more Surge when I'm bulking, less when I'm cutting.
