Been around the block and appreciate feedback from the same only thanks.
getting gear in amps of late and used to using vials. Heard that most folks used regular pins to draw from said amps, and after standard switch of the draw pin to an inject pin, without issue until about a decade ago when pins were first started to be recommended for both medical and anabolic use for amps.
I used my regular proto with several amps without any notable issue, but since then have begun second guessing if that is a safe way still? Anyone who’s had experience with amps predominantly in their aas use please chime in on what you do, ie; filter pin or regular pin.
