Anyone who wants to reap the benefits of BA without taking a product with it should look into UltraRep by AthleticXtreme. It gives you all the benefits without the harsh reaction from the body. Basically the difference is UltraReps uses Enterically Coated L Carnosine instead of BetaAlinine. BetaAlinine simply boosts the synthesis of carnosine in the muscle to keep the PH in the muscle more stable after the breakdown of ATP(which causes the rise of acidity from the excess Hydrogen Ions). Some try to just dose L Carnosine instead but during the digestion process in the stomach it becomes unusable by the body, which is why there is the need for Enterically Coated version, which allows for the breakdown to happen in the small intestine where all there is an Alkaline environment that wont destroy the carnosine. I used to just deal with the horrible sides of BA but never again. First time I used UltraReps I was sold!
