TNT, i have some needle questions as well

First off, I have needles left over (over 50) from last summer (summer of 2001) and they are inside my friends locker at univ. They are all in a box, and each one is still in it's wrapper. What i'm wondering is, do needles go bad? Basically, is there such a thing as having a needle too long even if it's still wrapped? Or is it better to by newer needles? They are 22G 1.5inch needles.

Also, when you say that the needle's point will be dull because it's penetrating the vial rubber, isn't the needle point also going dull from hitting the bottom of the vial/amp? Like sus amps, you can flip it over to withdraw (obviously the sus will leak out) so you must keep the needle upright correct? So the needle constantly hits the bottom of the sus amp. Also, how do you get every last drop of sus out? Doesn't some of the oil stay at the bottom of the amp? Stuff that you just can't reach/suck up?

Also, if i'm planning on injecting into the quads, like you said above, it's better to get 25g needles 1 inch. So is it a good idea to use the 22g needles i already have to withdraw the sus, and then switch to 25g to inject? Will the needle always fit the new syringe? As long as they are both 3cc?? Cause the ones i have now are 1.5 inch, and i want 1 inch for quads, still okay?

thnx
