Exactly.....I felt like shit when I went to EOD injections because the level of Tren was constantly going up and down like a yo-yo. In my opinion if you are going to take it, do it right and do it every day. I rotate left delt, left glute, right glute, right delt and then start over. Four days between injections seems to be enough for me. It starts to get really hard to push the shit in by the time week six rolls around though. My wife is a nurse and she does all my injections for me though so it is easier for her to make sure she's not sticking me in the exact same place every time. If it wasn't for her it wouldn't be as easy.
