so you spoke to another doc that wants your range just above 300...sounds weird but convince him that you can inject yourself and you will be able to deliver that range for him if necessary when the time comes
another option...another doc entirely that will shoot for a mid range...i would use that insurance that you have, thats what its there 4...im glad there are clinics out there and not trying to down them because they are a nice option but like you said your insurance aint gonna cover it
good luck...either way...your gold bro
