can u leave juice in the dart for a long amount of time?

can i draw up prop/eq and shoot it 8-12 hours later? or how about a day later? also is it ok to lube the needle then cap it and inject later on? i did this bcuz i was ready to shoot and someone came in the room and i have a lubed needle that is capped and i need to shoot it later.

lubed needle ?? how exactly do you lube a needle ?? KY ? vaseline ??

it's okay to preload, but make sure it doesn't sit there for an extended period of time. bacteria is everywhere.

lubed meaning drip a little juice out before poking.
