In the world of competitive bodybuilding, anything that can give you a leg up on the competition is more than welcomed. If that means turning to the Internet to purchase breast milk from mothers with an extra supply, then so be it. When stay at home mother of three, Lisa Charbonneau, found out from a bodybuilding cousin just how lucrative the online breast milk market was she knew she had to get in on the newest weightlifting trend.

“I have a 5-month-old and have been constantly pumping excess breast milk which I have been storing, and my deep freezer is nearly overloaded. I do not drink, or do drugs, and I take a multi-vitamin daily,” Charbonneau explained on a Craigslist ad, where she has gone in hopes of peddling her excess breast milk.

Charbonneau plans on selling her product for around $1 an ounce, which seems like a reasonable price compared to more legitimate sources. OnlyTheBreast.com, a website that facilitates mothers looking to buy, sell, or donate their natural breast milk, currently charges $2.50 an ounce. While Charbonneau and other breast milk vendors market their product as the most effective post-workout supplement money can buy, medical professionals recommend that curious weightlifters err on the side of caution.

A recent study published in the journal Pediatrics revealed high levels of bacteria, including Salmonella, were found in breast milk purchased from two popular online distributors. Although Charbonneau and fellow supporters say breast milk is a perfect source of healthy fats, complex carbohydrates, and protein, we should think twice before consuming anything we purchase from a random online source that is not FDA-approved.
