This will only appear in PUB MED as a citation, with no text at all, because it was just a letter, not a formal research article.
However, the text has been provided by the company who stands to benefit from having the text available. I doubt that the publisher would appreciate this; it’s probably a copyright violation — but hey, we get to see some detail about the series of 19 patients Dr. Simmons treated with the stuff, 12 of whom got much better. Please read the rest of my roughly-1-page story about TrueHope (you probably just came from there) before you go surfing around the manufacturer’s website, though, okay? — because there are multiple points of view you should know about before you do that.
