Anyone can mix chemicals in a test tube and claim it’s the cure for something. That’s the easy part. Proving it’s safe and effective, that’s what requires a lot of capital expenditure. This statement is a drastic characterization, but you could say “half a dozen PhDs can form reasons to believe they may have found a cure for something”, and the paragraph would end the same.
That means they have gone all the way to prove it’s safe and effective, and now have to convince the regulators.
Can anyone find the studies?
