It is produced primarily by the liver in response to growth hormone signaling and acts as the major mediator of GH's anabolic effects.\u003c\/p\u003e\n\u003cp\u003eThe most common research analog is IGF-1 LR3, in which an N-terminal 13-amino-acid extension and an Arg³ substitution reduce binding to IGF-binding proteins, prolonging its biological half-life.\u003c\/p\u003e\n\u003cp\u003eIGF-1 has been studied extensively in research on cellular growth, differentiation, anabolism, glucose metabolism, and neuroprotection.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eFor research purposes only.
