A lot of people didn’t trust the Peloran when they showed up.  Still don’t actually.  Many groups tried to reverse engineer their treatments in fact.  The results weren’t amazing.  The Russian and Chinese Treatments for example have some kinda crazy side effects.  Very rare of course or they wouldn’t still use them.  But dwarfism, giantism, and a lot of other ’isms like that show up with them.  One side effect they don’t get is the Ageless.  We’ve got no clue why.
