One of the hottest areas of supplementation in anti-aging research of the use of growth hormone. An older study showed that growth hormone aided weight loss and made the skin tighter. This was equated with reversing aging.
A recent study suggests that growth hormone may not be a great contributor to a longer life. The hormone increases insulin-like growth factor-1 (IGF-1). A recent study suggests that elevated IGF-1 levels may increase risk of cancer and decrease lifespan.
Sales of growth hormone totaled 3.5 billion dollars in 2011. Those who are spending their money in this way may be receiving no benefit. The use of supplementing with hormones is fraught with risks and unintended consequences.
