Your right, in my research the tropical and medpharm families are not linked. they may be owned by the same people at some higher level (both domains registered in the domincan republic, both use clinical solutions, both use dr. lynch, both offer same hydro drugs, etc.), but their ordering db's are definately separate.

In my opinion, you are not "double dipping" by ordering a 30 day supply from tropical makes you wait 90 days to reorder and then ordering another 30 day supply from medpharmx after 30 days has passed (which will also make you wait 90 days to re-order).

It would be different if you ordered two 30 day supplies from each of them at the same time.
