HOWASPiRATE

To pull the back of the syringe once its in the muscle, if you hit a vein then blood will fill it. Remove needle, replace the needle with a new one and choose another site to inject. Do not inject into a vein.

Good info, Cardi. Of course some blood would come back in, but if you hit vein it will flow easily back into the syringe. Actually, i've never aspirated and never had a problem. Maybe I'm just lucky.

How much blood would go in if i don't hit a vein?

when you aspirate, you should get a little air bubble in the syringe...not blood...if you do get blood, just pull out, relocate, and restick...

aren't bubbles bad?

Naturmade, its not an actual "air bubble" its vacuum. There no actual oxygen in the syringe when you aspirate. The suction of the vacuum brings the syringe back to the original position when you release it. Dont worry youll be alright.

On another note, when you load up your syringe, you might notice a few actual "air bubbles" that are very hard to tap out, dont worry about injecting those tiny bubble either.......a person would have to inject 2ml or more of air into a vein to cause a heart failure and die.

So lets say the syringe is right next to a vein when you aspirate, and when you pull back you happen to move the needle a little and then puncture the vein when you go to push the plunger in, how would you know you hit the vein then? Maybe when you drop to the floor or what, lol?

well bigcat, something like that.....

just be careful about moving the needle around when you're doing all that. personally, I'm careful of that cuz I'm paranoid about busting the fucker off in my leg or ass and having to get it cut out cuz I was stupid....
(FYI, its actually very difficult to break a needle)
