In this episode, Elwin does a deep dive into whether building muscle is actually good for longevity — and at what point too much becomes too much. He shares his own journey from being stick thin to gaining 7kg of muscle in five months, unpacks why there are no jacked centenarians, and reveals that the real longevity risk isn't the muscle itself but the things people do to get and maintain it: anabolic steroids, growth hormone, excess IGF-1, and even excess protein and methionine.
