Description

Igtropin (Long-R3 IGF-1) represents chemically altered form of the peptide hormone insulin-like growth factor-1 (IGF-1). The structure of this hormone is similar to that of insulin. That’s why it is called “insulin-like growth factor-1″. If you want to understand which effects are caused by the medication Igtropin, you should understand the essence of the hormone IGF-1

IGTROPIN (IGF-1 LR3) IGF is more effective at directly causing muscle growth and density increases than HGH. IGF can also be effectively used by itself and gains will still be easily noticeable. The study shows that the most effective form of IGF is Long R3 IGF-1; it has been chemically altered and has had amino acid changes which cause it to avoid binding to proteins in the human body and allow it to have a much longer half life, around 20-30 hours

Igtropin IGF-1 is a peptide roughly the same structure and size as insulin, or about 70 amino acids long. It belongs to the peptide family of substances identified as growth factors. It is a highly anabolic hormone released in the liver as well as in peripheral tissues such as skeletal muscle. In the body, IGF-1 is released in response to the presence of Growth Hormone (GH). After intense resistance training, the body experiences a surge in GH and IGF, and this is one way that new muscle is built. Although GH is considered to be highly anabolic, in actuality, IGF-1 is suspected to be responsible for the primary anabolic activities of GH. 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 muscle fibers bigger, it makes more of them as well! Although IGF-1 is very potent at building muscle and burning fat, the Lr3 IGF-1 version is roughly 2-3x as powerful. Lr3IGF-1 (Long R3 Insulin-like Growth Factor-I or Long R3IGF-I) is an 83 amino acid analog of human IGF-I actually comprising the complete human IGF-1 sequence but with the substitution of an Arg for the Glu at position 3, as well as a 13 amino acid extension peptide at the N-terminus. This makes Long R3IGF-I significantly more potent (2-3x) than IGF-I in studies, because it has a lower affinity to be rendered inactive by IGF binding proteins, and consequently more potential activity in the body.
