Pre load?

Can I preload the pin a day before and recap or is there a bacteria issue?

If you kept it in a completely sterile environment.. sure why not. How are you planning on doing this though?

It doesn't take long to draw my friend, just play it safe and do it immediately before hand

I pre load for the week. As long as the cap is on good your gtg. Hospitals pre load shit all the time and that's the least sterile place you will find.
