Funny you think adding oil that blocks blood flow and kills actual tissue is going to improve his arms
I agree with you that Synthol looks worse, B. Hank.
But it was bodybuilding great and Mr. Olympia runner up Nasser El Sonbaty that said in an old episode of "Pro Bodybuilding Weekly" radio/podcast that Nasser said synthol is as common in the pro ranks as toothpaste. Then he amended his statement and said that Synthol was as popular as toilet paper! Lol!
Nasser himself obviously used Synthol...but IMO, it made his arms look much worse. I agree with you that Ron Harris' arms could look much worse with Synthol applied, but that doesn't stop many people from using it anyway, in an attempt to bring up a weakness.
The first picture is Nasser El Sonbaty presumably without Synthol, and the second photo was taken when he had been abusing Synthol for at least a couple/few years already.
