Just wanted to update everyone that for the past week and half I have been doing MC IGF into my triceps with great results. My triceps look fuller and rounder allready, and my arms have increased in size (1/4 inch) doesnt sould like much but any increase is good. Im going to do this dose (100mcg, 50 into each tricep ) and see if I can get a solid 1/2 inch increase...Also, just to note i have been doing this post workout....
