I'd eaten many Grow! bars, but then let the habit lapse. I just got the free Metabolic Drive bars 2 nights ago; placed an extra order just for the deal with 2 tubs Low-Carb Metabolic Drive powder, 1 Surge, 1 Power Drive, 2 ZMA. When I picked up the box from my porch, I couldn't believe how heavy it was. That little "brick" of bars packs a lot of weight into a small package!
And now I have to say yes, the Chocolate Chunk is amazing, and I'm sold on always having some around!
