Which Syring filter do I use??

I am gonna fill up 20 pins worth of test E, I am gonna buy a 50ML SEALED vial from the AAR site.. Do I need a filter thing? Or can I just punch a hole in it and INJECT???

If I need a filter please send me a link to which one I should use and how the hell do I use it. Thanks!

depends on where you got the test e from.
if its homemade then you will need to filter with a .45 or .22 filter.
if it is from seperate vials and you want to transfer into a single vial then you can just straight transfer them.
