Most bars aren't that good. Make a protein shake with oats and its basically the same.
Thermorexin is the best fat burner around. With Ephedra gone they are less effective.
Most like Optimum Nutrition 100% whey and Muscle Milk for protein shakes.
The best creatine in my opinion is micronized creatine by AST. However some believe any creatine with NO2 like SAN V12 are best.
