Andrew Huberman (@hubermanlab) says he has parents asking him about giving HGH to their teenagers "all the time" now: "People who have kids that are much shorter than their peers nowadays often, and I'm not suggesting doing this, will delay puberty in their kids. They'll sometimes give them growth hormone." "When you start playing at-home endocrinologist — and now it's very easy to find a physician that will work with you on these things — you're playing a dice game. So you have to think real carefully about when and if to do these things."
