I am a vegetarian and very committed but I am also a bodybuilder and have struggled to find ways to get all the protein I need to make my muscles grow.
I began using creatine about 2 years ago and the results have been fantastic. I am bigger and stronger than I have ever been before. I bounce back from tough workouts in no time and my muscles are defined in a way that I didn't think a vegetarian could ever hope for.
I know that some people are not crazy about supplements, but the simple fact is that it is hard to really increase your body mass using bread and veggies alone.
