I feel like this spin on intranasal ROA of bupe should be further documented. I, personally, choose to insuffulate my bupe (in form of Subutex) and the spray pump/saline method sounds as if it will not only absorb better, but will 'clean up' the entire process by leaving less binders/fillers in the sinus cavity. Has anybody come up with a preferred bupe:saline ratio that works well and doesn't clog the spray pump? Obviously there are many different factors that come into play when you consider which brand of pill you are using etc.. I use generic subutex from Roxane (the large, round pills.) I imagine the oval, smaller ones would be preferred but unfortunately most of us can only get what is available. I'd like to hear people's end-results and make this thread complete!
