Exactly, that is why some pros can get out of the sports still without medical problems even after decades of abuse because they have the genetics to tolerate huge doses.Genetics are the main factor I say. Not everyone can be mr Olympia obviously. I know a guy who ran around 2 grams of gear and didn’t change much in appearance than when he ran 600-700mg of gear. Hence why I asked this question to begin with
There was an interview with Roman Fritz where he said he never had acne and hematology problems even while pushing doses.
It’s all genetics generally, if there are people who can be party animals downing liters of alcohol and doing lines every night but still end up with healthy organs, there are bodybuilders who are bound to resist AAS long term damage too.
