I'll use the same 20g to draw with a few times. I always use a new pin to inject. I haven't heard of anyone having problems when they use the same pin to draw with repeatetly. if anyone has, I would like to know.
My source keeps slacking on the pins, and I'm running low. I'm thinking I'll just use the same pin for three withdrawls. Anybody ever heard anything bad happening from this? It's deca
If you have access to plenty pins I would recommend a new one for shooting every time, you can blunt a pin even on a rubber stopper, plus there is the risk of losing its sterility by touching the amp and stopper etc.
I have done it with no problems, same needle for 2-3wks. I dont advise it, if you do it keep the tops wiped down and don't let the drawing needle touch anything that is not sterile.
You can get needles from here in a couple days.
