But the claim that I was addressing was that he turned PRO as a natural
Passing drug test is not the same as being natural, we all know this.
Ronnie transformed more than anyone else of his time from his amateur stage until he reached his peak, but it took him more years than the rest. Levrone, Francois, Dillet or Flex reached the top quickly, in 2 years or less.
What this suggests is that he wasn't using everything the other guys were using when he was trying to become a pro.
It also takes balls to want to compete by passing drug tests when it's not mandatory and you have other options.
Kai competed in natural feds in the 90's, then turned pro and needed 4 years to get his name out there. Like Ronnie, he became a monster gradually.
