3 cc's in the glute is about the maximum I would use, I don't think you could put 5 anywhere. Just spread them around, but unless you are using something like 50 mg/ml. EQ then why are you using that much anyway?
I would keep it 2cc or lower. Anything over that builds up a lot of scar tissue....over time. But I guess I could inject bout 10-20ccs in one area if I really wanted to though I guess... ..Hope that answers your question!
