IGF-1 LR3 Human Bodybuilding Anabolic Steroids For Muscle Gaining and Muscle Growth CasNO.946870-92-4

IGF-1 LR3, also known as Long R3 Insulin-like Growth Factor-I with 83 amino acids, is a human recombinant, single, non-glycosylated analog of IGF-I 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. Due to this, it has been suggested that IGF-1 LR3 is more potent than the IGF-1 in many aspects such as increasing amino acid transport to cells, increasing glucose transport, increasing protein synthesis, decreasing protein degradation and so on.

IGF-1 belongs to the peptide family which has a same structure and size as insulin. It is a highly anabolic hormone that is released in the liver as well as in the peripheral tissues in response to the GH so that a new muscle could be built. The main work of IGF-1 is to build new muscle tissues by promoting nitrogen retention and protein synthesis. IGF-1 not only makes muscle fibers bigger, but also makes more of them. IGF-1 has potent effect on fat metabolism and helps the body to burn fat rapidly. It also improves mental functions such as reflexes and learning ability.

IGF-1 has a very sensitive and unstable property that’s why it is used rarely because it has a very short term life of only 10 minutes. That’s why a substitute of IGF-1 referred to as Long R3IGF-1 or IGF-1 LR3 is used. IGF-1 LR3 has longer life. IGF-1 life time is increased from 10 minutes to hours in IGF-1 LR3, so that the users can get away using a smaller amount of IGF-1 LR3 and does not have to use it as frequent. Long R3IGF-1 is in the form of lyophilized powder form or already reconstituted form.
