Aspirating

[Acer97]

I know aspirating isn’t necessary but I’m curious why when I aspirate air bubbles stay in the syringe. Isn’t it in a vacuum state so where is the air coming from?

Perhaps it's dead space and not actually air? Or maybe it's not actually a completely airtight seal like we think.

Aspiration is drawing back the plunger once the needle is inserted. How would that affect bubbles already in the syringe?

No lol Im saying when I aspirate bubbles start entering the syringe and stay there when I pul back

When you inject your needle into muscle and pull back, bubbles start entering the syringe?

Two possibilities:

-you are using a luer tip and pulling air in (if you are using an insulin syringe this is not an issue)

-you are pulling the plunger back too far, and bubbles are forming in solution due to the high vacuum.

Anything wrong with bubbles forming? Will this affect the testosterone?

Just stop aspirating. You’re wasting your time. The movement alone will place the needle in a different spot anyway once you aspirate.

No.

Why do you aspirate anyway? Are you using harpoons deep IM?

I never aspirate. I have tried it a few times. It does look like a bubble can form. I definitely would not be concerned and still inject. That is if there is no blood.
