likely muscle-wasting,
So he’ll need to do something drastic to put on muscle. Sure he could blast, but Elon is a busy person. He’ll want the biggest transformation in the smallest possible time. His cardio is hopeless anyway (see above: busy person), so that won’t be a factor in what compounds to deploy.
I predict that if Elon ever decides to fight Mark Zuckerberg, then he’ll be the first billionaire on Tren.
