Check your Grow! label. It also contains soy lecithin. I doubt the Biotest crew would be trying to load us up with estrogen. Correct me if I'm wrong, but the lecithin/fat part of the soybean is fairly innocuous. The protein (and especially the isolated protein) contains the phyto-estrogens. I hustle vitamins for a living and one of the top menopause reliefs is a regular dose of soy isoflavones.
Don't sweat the lecithin, oil, miso, and soy sauce. Avoid the isolated protein like the poison it is.
