Ok this one surprised me. I saw this on Netflix this weekend . They have a new series called "unwell". Talks about various alternative medicines and some of the down sides.well episode 3 was on breast milk. They had a women that was a hyper lactator. and she said she produce typically 70 oz every morning ( WOW) anyhow she sells and donates breast milk . mostly to women who can not produce enough ( good for her, Seriously how can you say anything bad about feeding infants ) . But then they talked to a bodybuilder that was taking it as a supplement. BTW if you are doing this, a lab did tests on some of places that were selling it , and the results are very disgusting.
I could understand more if you knew the source. but I would also think that would make it weird too.

But are any of you doing this ?
the other thing is wouldn't breast milk be higher that estrogen?
