I think it's possible for some people and not for others. The vast majority of us may not be able to, but I believe some people can. Didn't Arnold have like 21 inch guns or something? Pretty sure they didn't have synthol back then right? I am a little curious if site injection matters. Cause just like you Plang, I feel like as soon as I started pinning my quads with prop they started to get better. I sure as hell would stick my bicep if it would work, I'm tri dominant.
