Needles and ampules

Do you have to switch needles when using ampules. I know that when using a vial this is common practice but, is it necessary when using amps.

I wouldn't change needles if i was using an amp.

I do change the needle. Honestly though it is not ever truly "necessary", regardless of whether you use amps or vials.

then why change em

Yeah i change, just habit.....

To have the sharpest and cleanest needle possible. :)

so what size do you guys use to suck up the test

I am currenty cycling with test e in ampules. I use the same 23g needle to draw and shoot it may take a little longer to draw, but I'm not in a hurry. When using a vial pushing the needle through the stopper will dull the needle that is why it is recomended to change needles

I use 18g to draw from amps then switch to 23g. I noticed that if I hit the glass with the needle it was harder to get in when I went to inject.
