aspirate air?

Guys,

Quick question about aspirating.

I'm gonna inject in my glutes...Upper right sections which I understand carries a very low risk or hitting a blood vessel and veins.

With aspirating, I understand to push in, and then pull back a little to see if there is any blood...Obviously if there is blood, try another injection site...

What happens if there isnt blood? Do you draw anything from your body? Do you just draw air?

Apologies for what must seem like such a dumb-ass question, however Ive done two cycles before, injecting in my ass both times and never aspirated cos I wasnt told too...Never had problems though!

you may see a few tiny bubbles.. dont pull back much.. just a tad..
if your in a vein blood will rush in
