Whats up guys? This is my first post, but I have been here reading for about 6 months. So I am a newbe, but not really. As far as the HIV contaminated vials, that is pretty far fetched. HIV can only live outside of the body for very short periods of time. And I am pretty sure if I saw any blood in an amp were it looked like somone may have tried to contaminate it with somthing, I would not buy them. Hey, but maybe their is somthing I dont know about this. I think you sould be more worried about an bac. infection, rather than a viral infection.
