Is a half inch needle to short for delts?
I prefer 1.5 inch pins. I bury them in shoulders, glutes, quads.
I prefer 1.5 inch pins. I bury them in shoulders, glutes, quads. That way it gets into the deep muscle tissue. I would be hesitant to use .5 inch pins except in biceps or triceps. Google syringes and you can buy them easily. They are not illegal to purchase or possess.
In my case anything more than 1/2 in would probably hit nerves or bone in the areas where I inject.
