FYI, soy protein is not near as beneficial as whey, casien or egg proteins. It is not a complete protein.
I dont like the cold of milkprodukts. And what exactly is missing in soyproteinisolat?
Google the amino acid profiles of each of the different proteins. There are more than I listed. Or read up at Bodybuilding.com and like websites. And about Scooby, I don't think so.
