My options for Whey protein are limited because I live in a foreign country with only a couple of places to get protein shakes.
Today I went to buy Whey protein but they were sold out.
My only viable option (a low carber) was 100% Soy Protein by a company called "On" based in the USA.
What exactly is, soy protein?
How different is it to Whey?
Is it much worse than whey?
