I'm after a bit more advice - now I've decided to SI I'm nervous about using. The correct procedure regarding needles.
I've already been given some great advice here, but my issue is regarding the use of a filter needle when drawing hydro up from an ampoule. All the reading I have done suggests you can get slithers of glass from breaking the top of the glass ampoules into your injectable solution. I was just wondering if anyone else uses filter needles or just a blunt fill needle before swapping to the actual injection needle?
Thanks in anticipation.
