Insulin-Like Growth Factor 1 (IGF-1) DESCRIPTION Insulin-like growth factor-1 (IGF-1) is a single-chain polypeptide of 70 amino acids. It is a trophic factor that circulates at high levels in the blood-stream and mediates many, if not most, of the effects of growth hormone. Although the main source of IGF-1 in the serum is the liver, many other tissues synthesize it and are sensitive to its trophic action. IGF-1 was called somatomedin in the older literature. IGF-1 and insulin have similar three-dimensional structures. IGF-1 appears to influence neuronal structure and functions throughout the life span. It has been shown to have the ability to preserve nerve cell function and promote nerve growth in experimental studies. Because of these properties, recombinant human IGF-1 is in clinical trials for the treatment of amyotrophic lateral sclerosis (ALS). Recently, recombinant human IGF-1 has entered the dietary supplement marketplace, as have recombinant human growth hormone and several so-called growth hormone secretagogues or releasers. IGF-DES is the most potent form of IGF-1 on the market today. THIS PRODUCT IS NOT FOR HUMAN USE NOR IS IT INTENDED TO TREAT PREVENT OR CURE ANY DISEASES.
