How harmful is it if there is some bacteria or other pathogen found in your AAS and then it is injected? Even if there is bacteria in the AAS how harmful is this? Can a normal immune system typically fight this off if there happens to be a bacteria, pathogen, or virsus found in your AAS? I ask this becasue I question some of the purity of some UG labs, and just wondering how bad it is to use this gear even if it is a little contaminated. Also, will a abscess always form if the gear is not 100% clean? Thanks
