I like vials the best
Satchets for 2 much work in them for me
Amps r harder 2 take .5ml out of them u hav 2 leave the rest in a syringe & change the needle
Multi-use, since I've never tried amps or sachets.
I just p/u some propionate and Sustanon in amps......how do you break them open? I figured you just break the top off, but what is the best way of doing so?
