I have test e in 250 ml ampules. I understand to open them one has to score the glass at the narrowest part of the neck with a sharp serated knife and then draw from amp.
My questions are this:
1) Best way to score cleanly.
2) Even of looks like a clean opening (I.e. no apparent small glass chips) how can you make sure you are not drawing some small glass frage without noticing...
Thanks!
