Aspiration + Blood?

I have a question about aspiration when it comes to blood being in the syringe. Personally, I’ve never had this problem on my first cycle, but it does worry me.

So my question is, if you aspirate and see blood, should you continue to inject into the muscle with the same oil (Test E) + blood in the needle (AFTER you pull the needle out of the spot where you hit the vein, of course), or is the Test E oil ruined?

In theory there will have been no contamination and if its an intramuscular shot there is no issue with a little bit of blood being absorbed into a muscle.

My God, people aspirate before they inject??
