I just did my test injection yesterday. I stuck in the needle into my glute, aspirated then started to inject. Needle moved around a bit so i asperated again to make sure i wasnt in a vein and all was fine. Im thinking i didnt check close enough because when i pulled it out there was a little bit of blook in the pin and in the syringe. Did i hit a vein? I didnt feel anything but im worried if i did inject in a vein or if i wasted any gear????

Thanks
Julian
