Soy XT & estrogen question

Hey Alex,

I was wondering, you've stated in the past that Soy XT actually had anti estrogen properties. What would be a minimum percentage you would need to use in a custom blend to get these effects? Or is there an ideal percentage? I mean, I'm sure 100% would be best obviously, but that would take away using other great proteins. Thanks.

Only a very small amount of isoflavones should block estrogen receptor sites. I would try to consume about 10 grams of soy xt per day.

So like in a formula maybe 20%
