I am part of a testing group that is attempting to answer this question. I am not sure that I will be permitted to share the results publicly but will at least give you a thumbs up or down. I've pinned 3mg (so far) out of one of them and I am still alive.I appreciate that, chmuse. I'd really love to be able to use it, so I think I'll take your advice and hang on to it to see how this all plays out with future tests. I can use the second batch first.
