After the first cycle, I went on 4 points, 1 week left side, ass cheek then rear delt, 2nd week other ass cheek and other rear delt. always go in a clockwise fashion, that way I never forget were I shot last. I've done as much as 3ml in my rear delt with no problems, but as said before I suppose it depends on the gear your using. I did prop and tren acetate in my rear delt once....oh my fuckin god, couldn't sleep on that side for 4 days. Brutal!
