Yes shoulder delts with 1/2. I use 31 gauge, but injecting very small amount daily. Tip is to rub shoulder vigorously for 30 sec to get the blood moving before injecting.Thanks man I appreciate ur feedback.. just one last question ..since I'm very thin and running out of injection sites , is the shoulder a viable injection site with a 1/2 tip??
I have very thin arms . I'm 5'5ft 125lbs
