Bicep pinning rocks ,,,I love the pump you get ,the swelling , the rush of knowing you just dropped 1.5ml in each bicep ....Hell yeh big brotha ,,,go for it , Jab that slin pin in there and do it ......
I started out just pinning .75 ml in ea one same day and then progressed to 1.5 ml in ea on pin days ,,,,Damn the stretching and pump is out of this world on bicep day !!!!!!!!!!!
