You do, however, the MDs do not. And if they are not using MDs, that is insane too. That they are injecting something without IRB approval is nuts as is, that any licensed MD in the US would do so is doubly crazy and I would like to never be practiced on by them. The medical field is a different beast than, say, putting on an aftermarket car-horn or putting super instead of unleaded into the gas tank. The vast majority of people, including nurses and other MDs, have no idea how a specific medicine works or the complexities therein. Docs are required to help them, not to hurt them, we've thought so for thousands of years. Yes, many may say that they are helping the people, but the large majority of other MDs, via the IRB, say that they are hurting them. I'm gonna go with the IRBs here and say this is crazy stuff and sets a very dangerous precedent.
