No i dont think Flex was FULL of oil in 93... AFTER 93 yup, although i hear what your saying about Esiclene in the 80s good point, Mattarazzo, Dillets, and Priests arms were MOSTLY Genetic and IMO it wasnt til there Places started going down-hill the Obvious signs of Oil use More so in the Delts was becoming more and more Evident and with Nasser and Flex there arms were taking on Ridiculous amounts from 97 onwards both Flexs and Nassers arms in particular looked Embarrassing in 99.
I think we're saying more or less the same, guys likelevrone, flex, priest, matarrazzo all have good arms naturally, but did supplement with oil, making them even freakier and bigger, and as physiques decline, becomes more obvious, as they may also play catch up with more oil
De mayo was another
I think (my speculation - I wasn't there with them)the major jump in arm size all the guys with the already massive arms, was due to a principle similar to fst7 nowdays, injecting to strech muscle fascia pre workout, and allowing to accomodate new size. Charles glass may have pioneered this, as many of his guys incl gunter attained new size in delts and arms, cormier too,
