Adam Clark-Joseph was standing in the kitchen of his apartment in Urbana, Illinois, when he sensed that something was off. His daily dose of medicine usually took effect quickly, but he felt nothing. This was the third time in a few years that a drug prescribed by his psychiatrist suddenly didn’t work properly.

A self-described nerdy chemistry guy (by day he is a finance professor), he took out some lab equipment and began extracting the active ingredient. “Being as generous as I could, this stuff had about a third of what it was supposed to,” he says. “It was just massively underdosed. Beyond it just being a health issue, I was also insulted.”

The drug he tested in his kitchen that day was a generic. A previous problematic drug had been brand name, so he knew just avoiding generics wouldn’t solve his problem. Clark-Joseph decided there was only one way to ensure the dose and quality of his medicine in the future: He would test each refill. But when he called around, he couldn’t find any company that would do the testing—at any price.
