Sounds pretty hardcore, would be murder to a quad or delt shot lol.
i did 5 cc's in glutes a few times. mix of test and eq.
3cc is max I have used(delts,quads,glutes) but if you had an ass like Ronnie or Kai I could imagine 5cc would be no worries
I have done numerous times 2.5 - 3 ml into the biceps. deca/test "blend".
Meso did you have better biceps site injecting that much there ?
