I have pinned 3cc in Ventrogluteal no problem. Same with my quad, I can't reach my glutes, my delts are fine till I go over 2.5cc...
Recently I have really liked triceps.
I rotate between VGs (which both of mine can easily take 3cc with no pain), quads (both seem fine with 3cc), delts, triceps... So I have a total of 8 sites..most of which seem fine with up to what you are injecting, although I don't think it is usually suggested to shoot that much in one delt, but I do it without issues.
You could split that between 2 delts for one day. Then another day one quad, then the other, then one VG, then the other, then back to delts.
My triceps get sore with much over .5cc so I wouldn't waste my time with triceps if I were you if you are using that much.
