Why do i get stomach aches after drinking EAS protein?

EAS has sold you the idea that you will be a better athlete because you use EAS. It's pure BS. Eat a healthy diet with lean protein and plenty of grains, fruit and veggies. There is no supplement or performance enhancing product on earth that comes close to the value of a healthy diet. These pricks are selling you 10 cents worth of unhealthy powder for $100. It's just a bunch of BS and you are spending money on garbage that is making you sick.
