"Is Surge any good?"
Let me put it to you like this, you could likely replace Grow with another good quality protein and shave off a few bucks, but you can't skimp on the Surge.
There has been thread after thread on this topic, just do a search.
Personally I'm such a baby about it now that if I don't have Surge I throw a fit and won't go lift. I use it according to JB's lattest recommendations (1 scoop Surge, 1 scoop gatorade, 5g creatin, 1 litre water durign workout, then I slam another immediately after). Also eat an orange or two an hour before training for vit C.
Not only are my gains improved significantly, but my soreness is limited if non existant, I may feel sore a day and a half after the workout for an hour or so but after that it's gone.
FYI I've tried a few Surge clones that were less than 5 bucks cheaper, and nada!
