Refillable injector pen

Does anybody know a source for carts with published manufacturing standards? Would love to know if the carts are made using USP Type 1 borosilicate glass, for instance. "Trust me bro" standards are insufficient for daily lifelong injections, sterility is only one concern. I tried asking about this on STG once and was attacked for it, lol.

Are there cartridges that are safe to use with oils or is this not possible? I understand that people have said standard cartridges start to degrade when exposed.
