Filter needles...

That's unnecessary.
Needles are very precise and amp bits, which are anything but true shards can't make the trip up. But even is somehow a perfect one in million did get in, it'd be filtered out by the second smaller pin. Of course you use the two-pin draw and shoot system, right?

I draw with a green and switch to a blue or brown (orange) depending what site I use.
I use Testoviron (Bayer/Schering). The amps pop perfectly. I've seen my friend snapping the head off a karachi sust amp. It was a messy affair, hence this post. I was gifted some Iranian Test E recently so wondered how well those amps would pop and it got me thinking. Always good to ask questions .

Thanks for the responses fellas...
