Rubber in My Vial


I was just about to draw and I noticed two tiny pieces of rubber floating in my Test. Obviously I'm not going to use this vial again, I'm going to bring it to my clinic and get another.

Never had this issue before, I've been on T for 6 months. My question is whether there's any good ways to avoid this in the future? I always insert the needle at a slight angle and try to hit different spots each time. The only thing I can think that I've been doing differently, is using insulin needles rather than the 23ga's I used to draw with. Are smaller needles somehow more likely to core the stopper?
