Do you think aspiration is necessary?
I've done hundreds of shots (glutes and quads only) during my life, but never aspirated a single one of them. I could pretty much feel when I hit a vein, it hurt instantly, so I would just pull back a bit and go ahead and inject. A bit of blood would come out after withdrawal, but then it was all good. Never had a cough or anything. So have I been extremely lucky?
Also what's the big deal if you DO hit one? It's not like your directly injecting into the vein, morelike you're piercing one all the way through and if you did inject, some would go into the vein MAYBE, the rest would be dispersed into the muscle around it.
Am I oversimplifying, or missing some other pertinent info? Thx bros!
