I have used my thigh, upper arm, and belly. I haven't noticed any difference in the speed or effectiveness of the site. I almost exclusively use my belly now, as it is easiest ... (also biggest?)

I am surprised, yet pleased, that the nose canula worked for you, especially at such a low flow rate. BUT, to increase its efficiency, (you might want to wash, and clean it first, LOL) don't put it in your nose, put it in your mouth. With it in your mouth, you can seal your lips around it, and insure that you get 100% oxygen, and none of the surrounding air, like you would, with it in your nose. I have passed this information on to lots of people, when, in an emergency, they couldn't get their hands on a non-rebreather mask.

I use the vials. I split that into FOUR shots! That's right, I found that all I needed was 15 units (there are 6 units, per vial) to abort a hit. I have also taken the new needle-less injectors, and the old standby, auto injectors, and shot them into an empty vial, and then take the shots as I normally would. In my mind, if available, the vials are the way to go.
