Insulin-like growth factor-I [Mass/Vol]
IGF-1 is a hormone produced in the liver in response to growth hormone (GH). It drives cell growth, repair, muscle gain, and insulin sensitivity, and plays a big role in recovery, aging, and anabolic signaling. It acts like a middleman between your brain's GH signal and how your tissues respond. Low IGF-1 can reflect under-recovery, stress, low GH output, or aging. Too high may accelerate aging or cancer risk if sustained long-term.solve real problems with clean design and honest materials.
