Sorry if this is a dumb question. Today I used a blunt-head draw needle (18G) on a fresh vial of Testosterone, which has a self-healing rubber stopper. I normally withdraw with a normal, “pointy” draw needle. Today’s draw needle had a difficult time going in, but I eventually jammed it in there. It now looks like it healed, but when I turn it over, a little bit of the medicine dribbles out.
Have I ruined the sterility of this vial? If so I want to make sure to not use it again (I have enough to do so, the cost isn’t a big issue) – but I just hate to waste good stuff.
