" DosePro is the world's only commercially available, single-use, disposable, needle-free, subcutaneous delivery technology."
The DosePro is the fFirst to market delivery system and has the advantage over delivery systems that are brought to the market after DosePro. It's the same way with first to market drugs. Do you think that Fosamax had to worry about Actonel in the bisphosphonate market? Nope, first to market always gets the bulk of sales.
