I was actually living and training in Venice late 90s and was with Charles, This was after 93 so flex might have pushed up dosages afterwards, but Flex did more than Paul and Chris combined With the winstrol back then, some injected some just swallowed the vet version you could get 20 or 50ml 50mg per ml vials, stuff could cork you pretty bad and water based injection have given people far more abscesses than oil. Plus none of them ever used HGH more than once, meaning as soon as they mixed the bottle they shot it, whether it was 4-6 -10 iu, they were always saying that the stuff goes off so quick so just shoot it all at once, their placings at the Olympia basically came down to their connection, the US Pharma GH was expensive and got everyone lean, they all wanted it, but hated paying for it and some didn't pay and then that forced them to use Chinese Jins which they overdosed on at 10iu a day, stuffed their Olympia prep as they couldn't get rid of the water from the Jins, you needed to drop that a few weeks further out, took a while and a few fried kidneys from lasix for them to catch on.
I saw what was happening with all of that then. throw in Nubain and retired.
