Description
Insulin-Like Growth Factor-1, termed as Long R3 IGF-1, is a human recombinant polypeptide chain of 83 amino acids which acts as a serum factor and indirectly stimulates the incorporation of sulfate into cartilage. It’s the most effective form of IGF-1.
IGF1 LR3 also known as Long R3 IGF-1 or Insulin-Like Growth Factor-I LR3 is a Human Recombinant, single, non-glycosylated, polypeptide chain containing 83 amino acids and having a molecular mass of 9200 Daltons. IGF1 mediates many of the growth-promoting effects of growth hormone (GH; MIM 139250). Early studies showed that growth hormone did not directly stimulate the incorporation of sulfate into cartilage, but rather acted through a serum factor, termed ‘sulfation factor,’ which later became known as ‘somatomedin’.
Myostatin (also known as growth differentiation factor 8) is a secreted TGF beta protein family member that inhibits muscle differentiation and growth. Myostatin is produced primarily in skeletal muscle cells, circulates in the blood and acts on muscle tissue, by binding a cell-bound receptor called the activin type II receptor.[1][2] In humans, myostatin is encoded by the MSTN gene.[3] Animals lacking myostatin or animals treated with substances such as follistatin that block the binding of myostatin to its receptor have significantly larger muscles.IGF1 LR3: Long R3 IGF-1: Insulin-Like Growth Factor-I LR3. Human Recombinant, single, non-glycosylated, polypeptide chain containing 83 amino acids and having a molecular mass of 9200 Dalton. IGF1 mediates many of the growth-promoting effects of growth hormone. Research studies have shown that IGF-1 causes muscle cell hyperplasia, which is an actual splitting and forming of new muscle cells therefore increasing muscle cell density.

IGF-1 LR3 is the primary protein involved in responses of cells to growth hormone (GH): that is, IGF-I is produced in response to GH and then induces cellular activities. One such example is muscle growth or hyperplasia. This compound also makes the human body more sensitive to insulin. It is the most potent growth factor found in the human body. IGF-1 causes muscle cell hyperplasia, which is an actual splitting and forming of new muscle cells.
The most effective form of IGF-1 is Long-R3 IGF-1. This formula has been chemically altered to avoid binding to proteins in the human body, and to increase the half life, approximately 20-30 hours.
