what siz needle for glute injection

hey lads what size should i use for glute injection would a 1 inch be be no good or should i go the inch and a half thanks

I would go with an inch and a half

1.5 is optimal

cheers guys is there a lot of room for error when injecting the glute not 100% on where to pin point the injection anywhere in the glute or not i was just gonna tense up and go high on the outer side???

tense up to find where to do it but relax when injecting lol

23x1.5 for me..

thanks

high and to the outside is correct
