why you should use a new needle

[PT]

Insulin syringe needles. Image 1, never used. Image 2, used once. Image 3, used twice. Image 4, used six times.

these are slin needles under a magnifying glass but it shows why it is so important to use a new needle everytime.

Good post. Most of us know to use a new needle every time for various reasons, but for any nay-sayers those pics are proof you can't deny.

who would be sick enough to inject sick times with the same needle, iv done it twice before and it hurt like hell
