No, I'd be worried about viruses. With common animal milks, I know there's almost zero chance any viruses present in the milk are capable of infecting a human. Obviously that isn't the case with human milk.
Strongly depends on how it's sourced. Would definitely give it a try if it's excess from a milk bank that's about to expire or if it comes from cultured human breast tissue in a lab. Would not try if it its from some random person or otherwise unclear origin though.
Also wouldn't make a habit of it, there's probably infants who would benefit from me not making it more scarce and expensive than it could be.
