29-30g slin pins in either 1/2 or 5/8 for delts.
I’m pinning 2.5ml each time (25g 1.5in; glute/delt rotation), would it be overkill on my delts to use 3 slin pins at a time or am I better sticking with a standard 3ml but just using 1in like a normal person?
I’ve done multiple jabs in the delt at one time. You could stick with a regular 3ml barrel I just feel goin 1.5" in the delt is unnecessary. Could try using more injection sites as well, quads are a good one.
Right now I’m pinning 2mls everyday so slin pins are really nice because I can hit some of the smaller muscles with .5mls and not cram 2mls in each muscle everyday.
