Previously I was using 18g to draw and 23x1” to inject. Now I’m using 21g to draw and 23g 1” to inject. When I pin delts I just cut the plastic needle cap in half and clip it back on effectively making the needle ~.5”. Keeps me from having to have two sizes for glutes and everything else.
That’ll work just fine. I used to go with 25g until I switched to insulin needles, but 23g was what I started out using for TRT. Pretty painless once you get the technique down.
