Excellent points Orlando, however as Joe explained

Excellent points Orlando, however as Joe explained on the last conf call, Oralyn is still going to take years of studies. We don't have those funds...yet. Let Mannkind get people use to alternative insulin, and when GNBT is ready, we can give them an easier way to take it and benefit from Mannkind's trailblazing.
