21? Wow, that's a harpoon!I use 21g needle for thigh and never have a problem.
Maybe I just haven't found that nerve spot yet lol...I actually seem to get a better result from the 1.5" ..honestly switched solely because that was only length 25g they had at the pharm..but then noticed better results from it oddlyYeah, I had no issues with injecting into my quad right up until it felt like a bolt of lighting hit me when I hit a nerve, of course I was using a 1.5" and I really did not need that, I know that now.
Now it's just shoulders and ass
If you’re shooting 1cc or under and on the leaner side try 29g 1/2” for deltoids. I had to start incorporating more sites since changing over to EOD and found that to be painless.I've found thigh to be my best spot , I alternate which side obviously , pinning eod....
one thing that I did change was going from. 25g 1" to 25g 1.5" ...I'm sure the 1" gets to the spot but 1.5 for whatever reason seems to get a better hold?? if that makes any sense ??...
I might try other spots eventually but the shoulder was a rough one for me for sure
