I think some of you misunderstood needto's post.
Most cmpanies get their protein from the same source, and protein is protein...BUT... SOME PROTEINS ARE MORE COMPLETE THAN OTHERS.
For example, Whey concentrate is only actually 78% total protein. Soy protein is missing certain amino acids. Some protein supps require bigger portions to get the total grams higher. Some proteins last longer, some are harder to digest, etc, etc.
So yeah, in a straight up comparison, there's no big diff. But in the case of something like BIG BLAST, you have super plasma serum which is far beyond any other protein source. And as it's "normal" protein it has cross filtered whey and whole egg -- more more ingredients most powders don't contain. So that's what makes it a superior product.
Hey, if you want cheap and tasty, buy some soy, and mix it with Bosco. It'll be cheap. The stats will sound good. It'll taste great. But it'll be crap. You're better off with food protein. But BIG BLAST is better than the protein from any food.
