Shorter guys
do better at strength performance than taller guys.
I follow the Olympics closely and Olympic weightlifting is always dominated by Chinese, Iranians, sometimes Germans. All the top athletes are short & stocky, and generally speaking the Asian/Chinese & Iranian build is short & stocky.
I am 1.90m with the typical Greek physique and I have to work double as hard to work my strength.
That said,
in every other sport I overtake shorter stockier guys. I run faster, jump higher, have more endurance, and in martial arts I have reach and height advantage.
Genetic predisposition is everything in sport my man. Especially at elite levels.
Forget being over 1.90m and being elite weightlifter.
Forget being a midget and being an elite sprinter.
That said, when it comes to Rogaine, he's just unhealthy on so many levels.
As countless people have pointed out, he's on so many red flags:

Terrible diet, mostly meat based

Various PED abuse

Does no cardio/wellness training (hiking in forests, etc).

Takes recreational drugs

Lives in his head and obviously insecure man (no meditation/breathing/mindfulness).
I give him another 10 years or less before he starts having heart attacks & blood clots.
