Looking for a really good protein shake? Here's one kind you can't buy at any pharmacy or store. The reason: it's freshly squeezed...breast milk. Lisa Charbonneau is a stay at home mother of three who sells her produce on Craigslist.

She auctions off her excess breast milk to the highest bidder. Her clients include mothers who can't produce and bodybuilders. Yes...bodybuilders!

The price for an ounce of breast milk starts at $1. “There’s a ton of vitamins, a ton of protein, a ton of nutrients in breast milk itself,” Charbonneau says. “I heard my cousin post something on his Facebook about breast milk being just as a good protein shake, if they ever stop making them.”

Would you buy someone else's breast milk and have it for yourself?
