^ WTF are you injecting into your delt for? the glute is easy as shit to hit IM, holds a lot more oil, and won't bruise easily.
Long-acting esters like nandrolone undec (deca) won't have any real benefit from spot injecting... maybe if it were nandrolone phenyl prop delts would be ok...
Shoot into your glutes with 23g 1.25inch pins. Divide your glute into quarters and then shoot into upper right quarter.
You really complicate things for yourself mate!
