i have shot with 23s using sauce. it works it will just take a
bit more time to inject meaning it wont go out of the syringe as fast. otherwise you should have no problem
I am the expert on 23 guage. That is all I use: glutes, bis, tris, delts, pecs, fina, winny, test, deca. It is the multi-purpose guage, just make sure it is long enough, if you have alot of fat on you then you need a 1.5" if you are skinny than a 1" should be fine.
