I have always aspirated but only one single solitary time, in 5 years, have I pulled blood into the barrel. It was in my delt.

Interestingly I was at the docs office with my wife the other day while she was getting a progesterone shot in her glute - the nurse did not aspirate.

I asked her about aspirating and she said, "I knew you were on steroids!!".

Kidding - I asked her about aspirating and she said that the "experts" have now changed their opinion on the need for aspirating and have determined that (in the glute at least) if you pin the right area at a 90 degree angle (straight in) you do not need to aspirate.

She didn't mention other sites.

For me, aspirating is quick and easy and as bros (unlike nurses) we are sometimes pinning compounds that can have pretty uncomfortable results if pushed directly into the blood - like tren for example.

However, having said that, each of the 3 times I've gotten tren cough directly after pinning, I had aspirated with no blood. So aspirating didn't effectively prevent the problem anyway.
