Draw and pin. An amp cracker makes breaking them easy and clean.

I use a 20ga to draw, then switch to a 25ga to inject.
Question for those of you who use or have used Amps... Once you crack the top off, do you use a filter needle to draw up the contents and then switch to a needle to pin with? Or do you just draw up the contents and pin??
Use an amp opener always.
