Something to look into, if you can get a DR to prescribe an 'odd' dosing that autoinjectors and such do not normally come in, you can sometimes find a pharmacy to compound it for far cheaper than the premade vials and dosing. But at least here in Canada, it has to be a dosage that is not normally available premade, it is a bit of a loophole. Since you will have to prep the injection yourself, you can still use a 'normal' dosage.
