Is Genotropin off patent?  Will ASND buy Genotropin from Pfizer?

I think they are off Patent. They have basically 7 players in HGH with very little to no difference between the products. ASND buying genotropin is very unlikely. Why would they?  They would also need to do a substantial raise if they were to purchase genotropin. 

I thought ASND's TransCon technology used Genotropin as the active ingredient. I do know the study was based on a comparison against Genotropin.
