[gilly6993]

whatever you use to shoot any other oil....22, 23, or 25.....length depending on the muscle...

 

[johnny tougharms]

if you have easy access buy a couple of each and try it....some oils will go thru a 27 no probs....glutes use inch and a half
quads 1 inch
bis tris and delts 5/8
the latter two both come in 25ga
