Then please elaborate on 'how it is used'. If you answer that they use synthol to create deformed muscles and lose definition then you demonstrate that it's you who knows very little of how it's used.
The reason why they use it is because it increases muscle size, shape and density whilst actually improving definition. It is a positive thing (for men obsessed with increasing their size) if used properly and in moderation. I can't understand why so many people cannot understand a very simple fact: most - probably all - of them use it, you're only aware of it on the rare occasions they use too much and fuck it up.
Because, Ronnie has always been know for his bis, that double peak has always looked the same, same as his triceps, and definition ofsaid muscle groups. Actually in one vid, his arms measured at 21 inches at a relatively high bodyweight, and looked smaller, which shows he wasn't training them as much...Also Ronnie is one of the most old school bbers there is. When Flex went the Syn. route, he looked different, but not that much, it was only after Shawn Ray had said Flex looked like he was stung by bees, did it become suspicious. Ronnie on the other hand has always had that dry look, even back in the early 90's. Tris and bis have ALWAYS looked the same.
And think many of them use it, especially those who aren't blessed with Phil Heath's or Dex genetics...
