Who cares how big your arms or how big his arms are? This is a funny ass thread, not a "how big are your arms thread.Plus if your talking about only me, I am willing to bet his arms are well over 18".A 18" arm is nothing to brag about son, my arms are still close to 20" and I havent used any anabolics in almost 3 years.Now back to the bodybuilding look-a-likes .
