First Pin Experience!! Not So Bad Beginners!

But what is that reason? From my understanding of what I've read in your link, they make it sound like a waste of time.
What I was going to say is, what damage can aspirating cause outside of the pinning process taking an extra 5 seconds?

Additional scar tissue as aspirating moves the needle around.

I was in the doc's office late yesterday and asked them about this. I was surprised to get multiple opinions from the nursing staff there. Some do aspirate, most didn't.

Seems the consensus was that hitting a small vein or capillary is not anything to worry about and that aspirating and finding blood would just be a waste of a dose and syringe. Obviously these guys weren't talking about injecting tren ace into their selves though.

I've had quite a few bleeders injecting ace into my delt (sure I would have aspirate blood) and suffered no ill effects so I just don't mess with it. Seems like a good way to wiggle the thing around and possibly cause a little worse PIP.

A "bleeder" when you remove the needle doesn't mean you were injecting into a blood vessel. It is much more likely that the needle passed through one as you were entering or exiting.

I did a Google search and found a study on the matter - linked below. Here is an excerpt.

Conventional syringes are also used to aspirate materials other than blood – synovial fluid, amniotic fluid, cells (via fine needle cytology), pericardial fluid, peritoneal fluid and cerebrospinal fluid (CSF) are examples8–19. This wide spectrum of applications for conventional syringes is all the more interesting in view of the fact that although used for both aspiration and injection, the syringe is actually designed only for injection20. A number of studies have concluded that a conventional syringe is a poorly controlled and non-ergonomic device during aspiration21,22. Possible lack of precision may result in local trauma and pain, prolonged procedure time, failed or incomplete procedures, accidental puncture of blood vessels or nerve bundles, poor sample retrieval and delayed diagnosis23–33. The ingrained use of the conventional syringe for injection and aspiration is to a large extent attributable to its low cost, widespread availability and lack of an effective alternative21.

It also provides many of the reasons for doing aspiration prior to IM injections.

True. I guess the tip of the needle would have to be right in there before it would inject into it.
