A new mum has told how a bodybuilder approached her in the supermarket and asked if he could buy BREAST MILK from her.
The mum was out shopping with her baby when the hulk made the strange request and at first she thought he perhaps wanted some milk for his own child.
But then the muscle man revealed that he actually wanted the milk to drink as a supplement to help him train.
The mum, called Rebecca, refused but, unbeknown to her, she had just stumbled on a trend for bodybuilders to bulk up on the high protein baby food.
According to reports in the States, dozens of fitness fanatics are going online to buy breast milk – which is widely available for sale on mums' forums – to help with their muscle building regimes.
Rebecca told CBS 2: "A gentleman walked up and asked if I was breastfeeding my daughter.
"He lingered for a minute and you could tell he was a little nervous to ask, and then he asked if I would be interested in selling him my breast milk
"I just sort of looked at him strangely and said: 'I don't think so, but if you need breast milk they have milk banks for that – to make sure babies get milk'.
"He replied: 'Oh, no it's for me. I'm doing bodybuilding and CrossFit'."
The owner of Northwest CrossFit in Seattle, Jake Platt spoke of this odd trend in protein supplements saying: "I thought it was a joke actually.
"I would never in my wildest dreams think somebody would be drinking breast milk for performance."
But online forums like Onlythebreast.com are filled with classified ads for 'men buying breast milk'.
A man from Portland, Oregon, said he buys and drinks breast milk for health and workout purposes. He said his friend, who is a doctor, introduced him to a life of fresh, raw, and natural products.
One mum who sells her breast milk online said: "My own personal opinion is breast milk from a human being is way more natural than drinking from another species' milk.
"I just find that they're very secretive. Even when they call me their numbers are blocked. They just don't want to be seen or known."
But paediatrician Lana Gagin warned: "I would discourage anyone from purchasing breast milk from those untrusted sources.
"The way this milk is stored and processed is not always safe. There is nothing in breast milk that can be of benefit to a healthy adult [and] there is nothing in breast milk that would enhance your physical performance."
