IGF1 is actually a natural molecular structure similar to insulin. IGF-1 is the abbreviation for Insulin-Like Growth Factor 1.Know in scientific circles as a polypeptide protein hormone, IGF-1 or Insulin-like Growth Factor 1 plays a vital role in childhood growth and stimulates anabolic effects (muscle building) in adults. There are 70 inter-connected amino acids that make up a single chain of IGF-1. IGF-1 is a hormone that is produced when the liver is stimulated by human growth hormone. When levels of HGH rise in the blood, the liver responds by producing more IGF-1. These higher “bursts” spur growth and regeneration by the body’s cells, especially in muscle cells. Increases in IGF-1 levels have shown positive effects on increases in muscle strength, size, and efficiency. When you do not have enough IGF-1 in your body, whether caused by disease, malnutrition or a hormone imbalance, your growth can be stunted. The primary purpose of IGF-1 is to stimulate cell growth. Every cell in the human body can be affected by IGF-1, but cells in muscle, cartilage, bone, liver, kidney, skin tissue, lungs, and nerves tend to be most positively affected.
