Shit son, I got moderate calves now, like 14 or 15" on a 5'5" frame, but 3cc's? HELL no! Till last week I would never put more than 1cc per calf. Now with new basically painless gear, I put 1.5cc's no problem, and will probably put 2cc's per calf today. I'm also going deeper than I used to. I use a 27g, 1.25in needle, put about 3/4in in or a little more, not the full thing though. I've noticed I can only do 1cc in delts with a .5 or a 5/8 in, but when I man up and use a 25g 1in, i can put 2.25cc's so far without problems. I have pretty good delts though if you look at my pics so that might help some. If you have smaller calves, i would start with 1cc per calf, then go up .25cc per shot till the pain comes back, then back it off. When your calves get bigger, then you can inject more. Make sure to massage it well and preferably shoot right before going to the gym to work that muscle, it helps to get the blood flowing and ease the pain!
