With Enhanced Games, Silicon Valley investors turn doping into a billion-dollar business pitch

LAS VEGAS — This week, in a city built on risk and reward, billionaire biohacker Christian Angermayer went about his wellness routine.

He injected himself with weight loss drugs, testosterone, and legal-but-off-label growth hormones, designed to reduce deep layers of fat and regenerate his cells. To feel more outgoing, he added the peptide oxytocin, typically used by doctors to stimulate labor. For focus, he popped a pill of his usual stimulant, normally prescribed for sleep apnea. He logged tens of thousands of steps, sprinting to meetings at his hotel and doing circles around a large swimming pool.
