I have been using Sustanon for the last few weeks and every time I crack open the ampule, as directed, I never get a clean cut line as in the demos. It is always a bit jagged, on the part of the neck away from the blue dot (Where my two index fingers are, if that makes sense).
I never thought this mattered but then suddenly got to thinking glass might be going into the vial. I have not been able to get the proper size with filters but have been withdrawing with a 23g needle in the hope that this works as a filter replacement. Am i just being paranoid? Obviously if it shattered this would be a no-brainer.
