IGF-1 Synthesis

Meaning

IGF-1 synthesis is the complex biological process, predominantly occurring in the liver, where the peptide hormone Insulin-like Growth Factor 1 (IGF-1) is manufactured in response to circulating Growth Hormone (GH) signals. This anabolic peptide is a critical mediator of GH’s effects on skeletal growth, lean body mass accrual, and cellular proliferation across various tissues. The rate of synthesis is a key determinant of overall growth and metabolic health.
