Here is a link to an announcement of the Phase 3 trial: http://www.bioworld.com/content/medd...hase-iii-trial

And just to amplify what Starznight said about not taking large amounts of the OTC version, please, please listen! The OTC products contain a lot of filler because even 10,000 mcg is a very tiny amount, so they have to have to add a substance to make up a volume large enough to form a pill. Often, that filler substance is something like calcium, which at the doses they recommend is harmless, but is REALLY dangerous if you take a massive number of them. It could even mess up your heartbeat. Please don't try this!
