Thread: Question about injecting into thigh?

I just started VA TRT (tested T @ 243) and using test e from here to blast and cruise. I did my (4th injection ever) first thigh injection today and forgot to aspirate. Blood squirted 1 time (maybe 1/4 inch high) then flowed after pulling needle out, NO OIL though. It happened fast but I do not believe it was in rhythm with my heart beat, so I don't believe it was a artery. I immediately covered with a alcohol pad and gauze.
What are chances I just injected oil into my vein/ FEMORAL ARTERY? I do not feel any chest pain, no coughing, no dizziness, barely any soreness of injection site and it's been 30 minutes.

EDIT : I believe I hit the Accessory Saphenous Vein according to Deep Femoral Artery Anatomy, Function & Diagram | Body Maps
