Why does locating sterile 3 ml cartridges have to be this difficult?! 
What I keep turning up is obscure sellers offering tiny quantities, making sterility claims that are hard to believe. Then there's Amazon and AliExpress - neither of which I really trust.
Is there really no trustworthy supplier for these? If not, why? Too small a market? Hard to manufacture? Blocked by FDA rules?
Earlier, someone said they get theirs from US vendors whose products carry a sterility indicator. Try as I might, I cannot locate these supposedly amazing, hard-to-find items.
