New Worries About HGH
Human growth hormone, taken increasingly by boomers who want smoother skin and better muscle tone, is coming under new scrutiny, thanks to some recent research. The Wall Street Journal reports that studies published this year offer the strongest indication yet that lower levels–rather than higher levels– of a compound related to growth hormone called insulin-like growth factor-1, or IGF-1, are related to longevity and lower risk of cancer as people reach old age. Wait, it gets worse. The Journal reports that “even supposed antiaging benefits may not truly be healthy. There’s evidence that the increased muscle from growth hormone doesn’t actually increase strength. Growth of muscle alone due to HGH use won’t necessarily improve functioning if the well-worn neural pathways to the brain aren’t repaired. And growth hormone does stimulate cartilage growth, but this can actually cause carpal tunnel syndrome in older people.” Yikes. There must be a better, if not easier, way to stay young.
