I don't get all the fucking drama.
You swab the bottle with some alcohol, draw up yo shit, swab the injection site, relax the muscle, needle goes in, apply pressure to plunger, pull needle out and rub the area. It's not FUCKING ROCKET SCIENCE HERE. What the hell?? Aspirate? Are you fucking serious? Maybe with a 27g sitting in your biceps, but why anywhere else? When was the last time a nurse aspirated when giving you a shot of anything anywhere? Aspirating is just to make newbs nervous about shooting into a vein, ask any junkie how tough that actually is to do right...Shit.
