I think we can all agree, he as made amazing progress in his muscle gains.
He has pushed the training and nutrition and drugs to the max. He is super disciplined. He has made a real good effort at keeping the waist tight. And he definitely had the freak factor.
At the same time, he is really coming close to maxing out on his genetic potential with the current protocols we have available. He may have only another 5% max to reach his absolute peak. I have a rough idea what his on. I think if he made a few small tweaks (increasing or adding tren and Anadrol) and then really pushing the volume of the training he could really hit the absolute peak.
