Polypeptides are chains of amino acids. Proteins are made up of one or more polypeptide molecules.
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.
IGF1 LR3 is also known as Long R3 IGF-1 or Insulin-Like Growth Factor-I Long Arg3. This 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).
Follistatin is fascinating protein that can increase muscle mass beyond natural potential by suppressing myostatin. Scientists first identified follistatin while examining porcine (re: pig) follicular fluid in the ovaries.
Myostatin (GDF-8) is a member of the transforming growth factor-beta (TGF-beta) superfamily that is highly expressed in skeletal muscle, and myostatin loss-of-function leads to doubling of skeletal muscle mass. It is now known that myostatin is a key regulator of mesenchymal stem cell proliferation and differentiation, and mice lacking the myostatin gene show decreased body fat and a generalized increase in bone density and strength.
Follistatin works by binding to and inhibiting transforming growth factor-β (TGF-β) peptides such as myostatin which is responsible for regulating and limiting muscle growth. It’s also worth pointing out that myostatin may have a regulatory role in skeletal muscle fibrosis; too much myostatin can impair tissue function and cause chronic disease in vital organs, tissues, and bone marrow.
ACE-031 is an investigational (experimental) drug that is designed to increase muscle size and strength by blocking proteins that slow down muscle growth. ACE-031 is a protein drug that is administered by subcutaneous injection.
Neuropeptide Selank is a synthetic derivative of the human body's naturally produced tetrapeptide Tuftsin. It is a hexapeptide whith a wide range of uses. It was first sinthesized in the late 1990's by the Institute of Molecular Genetics of the Russian Academy of Science. Selank is used as an anxiolytic in the therapy of anxiety and phobic disorders, including generalized anxiety. Its action is similar to that of mild benzodiazepins but without the sedative effects.
Delta sleep-inducing peptide (DSIP) is a neuropeptide. Neuropeptides are peptides neurons in the brain use to communicate with one another. This particular neuropeptide increases the activity and neuron communication in the area of the brain responsible for rest and sleep
Gonadorelin, also known as GnRH or LHRH, is produced by neuroendocrine cells within the hypothalamus. The hormone is secreted pulsatilely. Gonadorelin induces the release of LH and FSH from the anterior pituitary. After a transient increase, continuous administration of gonadorelin results in downregulation of LH and FSH levels followed by a suppression of ovarian and testicular steroid biosynthesis.
