Hey guys, first time injecting test (into the upper thigh). Scenario:
I've drawn up 1ml of 300mg/ml test e and cleared the syringe of bubbles. I've then injected into my thigh. I've been told to slightly pull back on the syringe once the needle is in to check I haven't hit a nerve. If I have hit a nerve, I should see a little bit of blood in the syringe. But when I pull back on the syringe, it creates a new bubble in the barrel.
Is this normal? I thought I was meant to clear the syringe of bubbles prior to injecting, so why do I end up with a bubble when pulling back on the syringe (as a safety precaution)?
Noob question I know — just hard to Google this one and want to be sure I'm doing everything right.
Thank you.
