IGF1 LR3 is a Long R3 Insulin-like Growth Factor polypeptide hormone that properties with insulin. LR3 is an altered version of IGF1 that and modified to prevent deactivation by binding proteins in the blood and extends the half-life.
IGF1 LR3 is a chain of 83 amino acids in length, it has the same complete sequence of IGF1 but with substitutions of an Arginine for the Glutamic Acid at position 3, hence Long R3. The variation in the sequence allows the IGF1 to avoid binding to proteins therefore having a longer half-life. IGF1 LR3 has a molecular weight of 9.200 and its molecular formula is C990H1528N262O300S7. Along with possessing some fat metabolizing effects the modifications in LR3 increase transportation of glucose and amino acids to cells and stimulates protein generation. Research testing has shown it brings about muscle cell hyperplasia (new cells splitting and re-forming to make denser ones). IGF LR3 being more effective at this as a whole, it also may increase nitrogen retention and increase neuro-functions. 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'.

IGF-1 LR3 is the primary protein involved in responses of cells to growth hormone (GH): that is, IGF-1 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.

This peptide hormone has the promise of becoming the ultimate fountain of youth (anti-aging).
As the world has finally caught on to the fact that world-class athletes from all sports have been using steroids and other performance enhancing drugs (PEDs), the athletes themselves have moved on to the next generation of substances; Stimulates muscle growth and has been shown to benefit the heart; Encourages the absorption of Chondroitin Sulfate and Glucosamine Sulfate (also found in Velvet Antler); Regenerates nerve tissue; Helps burn fat, increase protein transport into cells, and reduce protein breakdown; Improves the production of white blood cells; Decreases LDL Cholesterol
