Thanks for saying pinning in the calf wasn't bad. Until I read you saying that, I thought that would be too painfull to try. Just did my first and not bad and easy to see and administer. Don't know if I'll be sore tomorrow but thank you. I was loking for a second spot, besides quads, as most of you say 2x week pinning is better than one. I now have my second spot. Thanks again Bro.
