IGF-1 LR3: Long R3 IGF-1: Insulin-Like Growth Factor-I LR3. Research Peptide Recombinant, single, non-glycosylated, polypeptide chain containing 83 amino acids with a molecular mass of 9200 Dalton. IGF-1 analogs mediate many of the growth promotion effects of growth hormones. Research studies have shown that IGF-1 causes cellular hyperplasia, which is an actual splitting and forming of new cells therefore increasing density.
Purity: 96% by HPLC analysis. 1mg per vial IGF-1 LR3.
Tan Research IGF1 LR3 also known as Long R3 IGF-1 or Insulin-Like Growth Factor-I LR3 is a Recombination, 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. Early studies showed that growth hormone did not directly stimulate the incorporation of sulfate into cartilage, but rather acted through a serum factor.

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 system 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 long lasting form of IGF-1 is Long-R3 IGF-1. This formula has been chemically altered to avoid binding to proteins in the body, and to increase the half life, approximately 20-30 hours. The polypeptide Long R3 Insulin-like Growth Factor-I IGF1 LR3) is an 83 amino acid analog of IGF-I actually comprising the complete IGF-1 sequence but with the substitution of an Arginine (Arg) for the Glutamic Acid (Glu) at position 3, as well as a 13 amino acid extension peptide. This sequence change causes IGF-1 to avoid binding to proteins and allow it to have a much longer half life, around 20-30 hours. This analog of IGF-1 has been produced with the purpose of increasing the biological activity of the IGF peptide.” IGF stands for insulin-like growth factor. Among the effects the most positive are increased amino acid transport to cells, increased glucose transport, increased protein synthesis, and decreased protein degradation. When IGF is active it behaves differently in different types of tissues. In muscle cells proteins and associated cell components are stimulated. Protein synthesis is increased along with amino acid absorption. As a source of energy, IGF mobilizes fat for use as energy in adipose tissue. In lean tissue, IGF prevents insulin from transporting glucose across cell membranes. As a result the cells have to switch to burning off fat as a source of energy. IGF-1 builds new muscle tissue by promoting nitrogen retention and protein synthesis. This causes the growth of muscles through both hyperplasia (which is an increase in number of muscle cells) and mitogenesis (which is the actual growth of new muscle fibers). Thus IGF-1 not only makes fibers bigger, it makes more of them as well.
