Just as I was going to start a thread about this, I see YOURS! I actually just finished "testing" V 12. OK, the only advantage that V 12 has is better taste. Otherwise, PE gave me better pumps, more strength, and added 3 lbs of lean weight while V 12 added zero!
Does this mean that V 12 is a lousy supplement...NO. In fact, it is probably still one of the better sugar free creatine delivery systems available. However, I think PE is a product you can really "feel" working. I never "felt" the V 12.
My choice is PE!
(note: I may try Swole from Syntrax next and compare again)
