hold the plunger's wings with your thumb and ring finger and aspirate with your index and middle finger. also it kinds helps if you kinds shrug your shoulder that your shooting.
I hold it with hand then take 1 finger and push 1 of the sides of the plunger up. Soon as u see a bubble g2g..just wait until u can't reach ur delts anywmore!! Hhahahaha
use the opposite hand to hold the pin then use your other hand to aspirate..delts are easiest for me...glutes on the other hand, thats another challenge
moving the needle around can cause scar tissue i thought. i've never had to do a delt yet but when i do prop and ace in about a year or so i'm gonna have to.
I recently read some research that indicated that delt injections were not as effective as Gluteal injections because not as much of the compound is absorbed.
