You can get deep enough into the delt with an insulin syringe?
Yessir, half inch needle length. I think 5/8" is better, but when I first started pinning, I wanted to go with the smallest needle possible lol. I use a 23g to draw and switch it to the 27g. I used to back load the slin pins, but I'm sure you can imagine how tiresome that got.
Look up the ventroglutes! I love that location! Absolutely zero pain, and easy to see/reach. It's that tiny muscle that runs across your hip. It's all I use. I've yet to try pinning myself in the glutes, lol, shaky hands..
I like the delts myself. Never had an issue and can use a 27g slin pin.
Delts and chest are very easy. Look up spotinjections on Google.
Seems like a scary spot to pin, but I'll look into it.
You can push the oil through that small of a pin?
It's saying not to go too deep or risk hitting a nerve or bone. What pin length do you suggest for delt and pec? 1"?
