I do agree that just because the guy thinks it saves his life doesn’t make it so. But you seem to assume that he is simply wrong. The fact is that he was dying, they had nothing else to give, he received the drug, and he then made a turn around in chronological fashion.
I happen to think the drug is helpful in his setting, and THAT is why I posted this anecdotal case. There have been many others reported as well.
I do believe that the drug helped him, and he definitely wouldn’t have been able to get it even if his doctor and he wanted to try it in Michigan.
