Take D-Ribose with a Creatine product. Creatine increases ATP, as Ribose does, but uses a different mechanism to do so. In other words, they were synergistically. Therefore, if both are combined, then the results will be much more beneficial than just one of the supplements standing by itself. Ribose is more of an 'energy sugar,' which initiates the production of ATP, which fuels muscles. Calling it 'just carbs,' or 'just sugar,' is a little bit of an understatement.
Chew 1 tablet, 1-3 times per day, prior to exercise. You can double the dosage during training, if you'd like.
