I assume that was a typo/unwanted auto-correct, Hugs, and you didn’t really mean mistrust?
If you meant the MStrust, that is indeed a very good website in its own right, but doesn’t own or run MSDecisions (or never used to!), and isn’t the new name for it.
As far as I can tell, the MSDecisions website is just down. As there are so many new drugs recently available, I wonder if they’re having to re-write the whole content, which previously only really covered the injectables?
Or maybe it’s just a coincidence, and gremlins have struck. I’d keep trying.
