My doctor straight up told me I was not worth the time to complete the application for. At least he was being honest about how he felt. The legality of this is something that you would have to consider on your own - but I know that Pirenzepine tablets are available for sale through other countries - I have seen others talking about that online. DMSO is available in the US. That is what Win-San-Tor is using as a carrier for the Pirenzepine. I am not sure how you would go about mixing up a 4% cream with those two pieces of information though. I also know that Win-San-Tor does not have enough supply for their clinical trials yet - and that they are working on building it up (to include supply for the expanded use program). They told me they expect to have enough supply by early next year for the expanded use fda program.
