Using caffiene with a creatine product is not entirely useless but it may negate sum of the effects of the creatine or arginine in the product due to caffeines tendency to excrete water and constrict arteries.Hence it may just put an extra strain on water reserves. I use Crea-Pump from genetix nutrtion for this reason as it contains no caffeine and love it...wicked pumps. Ultimate Nutrition horsepower is also one to consider. Everyone is different so some things might suit one person and not the next. Ballistix from Anabolix Nutrition is also very popular as a creatine/arginine product.
