I have been in two others, MHAN now TSGX and CYTR, that both did this, multiple dilution rounds, between 2009 and 2011 under $1. Sooner or later MSTX is likely to be a 5-10 bagger, only question is when. I think people worry about a possible R/S here since they have a history of it.
I am still wondering what happened to the other drug they were ready to do an NDA on 2 years ago, that they claimed had a billion dollar market, no news on it since they started pumping the current the one they are focused on now that they bought from CYTR.
