Mifepristone (a.k.a RU-486) is used for cases of severe diabetes.
So yes.
You can mail order it from, Canada ,Mexico,India, and Israel just removed their restrictions on it. USPS is Federal they don’t open parcels and CBP only stops narcotics which their sniffer dogs are trained to find all other medical shipments are not opened that violates a slew of privacy laws. RU486 has other on label uses other than to induce miscarriages same for the other drug. This makes it impossible with privacy laws to force the disclosure of use to CBP or the USPS. Thst must allow the passage of medical shipments.
