Business Insider reported on the company first, while admitting there is little to no evidence that the procedure actually works.

But that hasn't stopped Amborisa creator Jesse Karmazin, from accepting payments via PayPal for the procedure: he is charging $8,000 for one liter of young blood and $12,000 for two liters. Karmazin, who isn't a licensed medical practitioner, told reporters last year that he had hoped to open his first clinic in New York City by the end of 2018. New York City has eluded him and instead he has opened locations in places like Los Angeles, San Francisco, Tampa and Houston.

Just like Theranos, the company also performed its own clinical trial to figure out what the effects of blood swapping would be. These results haven't been made public, but Karmazin has called them "really positive".
