Just asking because one of the blends of protein I've been using before bed is USN Pure Protein. It contains some soy protein (it's a mix of whey, milk, soy and a few other sources).
Is soy in this small amount going to be estrogenic, or do you have to take in huge quantities of it for that to happen?
