Some people are just genetically perfect for the sport they've self-selected themselves to be in or were saught out and created (like the Chinese NBA players, Yao Ming - both his parents are olympians and also tall as hell 6' 5.6 and 6'3 or so + he was mandated by the Chinese Government). Insane strength, insane speed, pretty good technique fighters might beat someone with perfect technique and practice of more years, especially when person A in this hypothetical has 20lb more lean body mass doing nothing with zero exercise, Some guys lift never, and bench 240 300lb etc, some train 2-10 years to do that or never do (my bench is weaker than most other lifts). Some people are naturally there without the hard work, but they're outliers. Some need to work like crazy for it. Sports, or whatever else. Some have 160 I.Q. and are born and bred to take up their family's business. Some are 160 I.Q., and relatively poor and fucked up. Person 2 has to "work harder" for less. It's the way it is. Some are 110 I.Q. and just born rich. Life's more complicated than a random health test, hair test or not.
2000g of carbs is insane. those are high number lifts for sure. The drugs do a lot. Ostarine, randro, etc... put permanent muscle on me or semi permanent. I'm sure if i lie down 15 years, most muscle would be gone. No drugs ever, maybe his numbers would be less impressive. Perfect genes for their sport + the right mix of drugs = crazy success. Like Arnold. But physical gains I got in like a decade plus, surely some got in weeks or months, or they're just monsters (they'd literally have to be a monster to be born doing a similar number of reps).
