No offense bro, but there is no need to cause panic for people, like you already have. You have people thinking about changing orders, and scared to try it. I and countless others have used qv with NO problems. Certain things don't work for all people, you may need to try a different brand, or better (cleaner) methods for injection, or perhaps you need to rotate sites more often. 50cc is a lot of fluid, I don't want to call bullshit, but it is a lot. Sorry you had a problem, but no need to cause panic for others.
