If your doing it right, 3cc should be no prob. I did 3cc for a few years in my thighs, then I started dating a gal who found my gear! After a discussion, and some truthful explanation, and some research on her part, she has been shooting my glutes ever since. (now my wife) When you shoot 4cc, you can feel it filling like a ballon in the muscle. I try to relax, lay around on my belly to let that tear start healing to seal 'er up after a poke.
