I did it all the time with the satchets. Just put your new needle on and shoot out some gear to clear like you would anyways doing only 1ml. It's harder to inject when doing delts or tris though having the plunger out further, causing you to have to press harder. Quads, no problem. When storing, make sure to turn syringe with the needle facing downward and pull back on the stopper, not allowing any of the BA in the gear to eat away at it. If you ever see a dark cloud formed inside, throw that shit out bro. I had some Tri-tren and went to do another shot 2 days later and it had already started to eat away at the rubber plunger.
