I currently pin ED for Test/Tren/Mast and need more locations to rotate in with delts and quads. I want to pin something I can see and reach easily, so glutes are out of the question. Already tried that, it didn't end well.
What locations are the least painful to pin other than delts/quads? Was thinking biceps, but not really too sure.
I will use slin pins for these injections and currently about 12%. I'm relatively lean.
