"Long[R3] insulin-like growth factor-I (IGF-1 Long[R3] ) is a Human Recombinant, single, non-glycosylated, polypeptide chain containing 83 amino acids. It is an analog of human IGF-1 comprising the complete human IGF-1 sequence with the substitution of an Arginine (Arg or R) for the Glutamic Acid (Glu or E) at position 3 (hence R3), and a 13 amino acid extension peptide at the N-terminus. This analog has been engineered with the express purpose of increasing biological activity. IGF-1 Long[R3] is significantly more potent than IGF-1 in vitro and in vivo. The enhanced potency is due to the markedly decreased binding of IGF-1 Long[R3] to all IGF binding proteins. These binding proteins normally inhibit the biological actions of IGFs. IGF-1 stands for insulin-like growth factor. It is a natural substance that is produced in the human body and is at its highest natural levels during puberty. During puberty IGF-1 is the most responsible for the natural muscle growth that occurs during these few years. There are many different things that IGF-1 does in the human body Among the effects the most positive are: . increased amino acid transport to cells . increased glucose transport . increased protein synthesis . decreased protein degradation . increased RNA synthesis. Storage of Reconstituted Peptides Once the peptides have been mixed or reconstituted into a liquid solution they must be refridgerated at a temperature of between 2-8c. If stored at room temperature they may begin to degrade after as little as 24 hours. Therefore we recommend storing them in the fridge as soon as possible after mixing. Stored in the fridge they will remain potent for around 8 weeks before beginning to degrade."
