needle question.

I use a 21 guage pin to draw the oil from the vial, and then switch to a 25 guage to inject...is it okay for me to use the same 21 guage pin over and over again?

thanks

i do that, but i doubt it's the safest thing to do.. it's prob best to use new pins all the time, even if one is just used to suck it up from the bottle

Why would you want to when they are so damn inexpensive? Pins should never be re-used for drawing or injecting period.

I Wouldn't, Use A New Clean One Each Time So You Lower The Risk Of Infection
