I heard someone say that one time, but I don't remember who it was. I was just looking for someplace else to stick my B complex. 1/2" 27 guage doesn't seem like it would be a big deal, but I was looking for opinions before I tried it.
Tried to find a decent image for you… now if I am looking at this correctly, I do mine in the flexor carpi radialis, very close to the elbow. During football training, our strength coach had the offensive linemen do an exercise where we faced away from the pulley; reached between the legs and simulated bringing the forearms up to the blocking position. I did this regularly and I have Popeye looking forearms as a result. Also keep in mind that with zambons, we’re only talking about using a 29g ½“insulin needle.
