I don't know all the Facts...But you do know that people just blame gear for abscess right away without just cause... ALOT don't take proper care when injecting.. A lot of people are more dirty then filtered gear at the injection site.. A lot of people inject gear in dirty houses, barns, shends, garages and wherever else they don't want anyone to know what they are up to.. Personally I know of two people that got abscesses.. both blamed the gear, however they would work all day come home take and shot not take proper precautions like use alcohol swab..Yet they blamed the gear ....Is there a link with pics of the infection/abscess can't find it?
