Somatotropin (Growth Hormone)

Somatotropin is growth hormone, the signal that drives muscle development, fat burning, recovery, and even anti-aging repair. It’s released in pulses, mostly during deep sleep, fasting, and intense training. Blood GH isn’t always the best way to measure long-term output (IGF-1 is more stable), but elevated or deficient values can give important clues. Think of it like your body's in-house "rebuild and renew" hormone.
