Great question. The way I'm currently looking at that issue is that the market for the US alone is huge (50% of the world market). By the time I satiate the US market, I will have been able to hire that expertise in. Another possibility is that if I sell directly to a distributor/radiopharmacy, I won't have to deal with any of that anyways.

Regardless, that is an important issue, but one I don't have to have a solid answer to for several years.

Great username, btw. ;)
