Insulin needles for IM? That would be really great.
Does it even reach the muscle?
I use whale harpoon for my ass, 1.5"
I use 1/2 and 5/8 insulin pins for delts, quads and pecs. As long as you’re not a big fatty it’s plenty long.
1 1/2” no thanks! My ass doesn’t like the long ones. [emoji15] I go 1-inch for the glutes. I started out using the 1 1/2” but there’s no reason.
