Molecular weight: 9200
CAS: 946870-92-4

IGF1 LR3 is a Long R3 Insulin-like Growth Factor polypeptide hormone that properties with insulin. LR3 is an altered version of IGF1 that and modified to prevent deactivation by binding proteins in the blood and extends the half-life.
IGF1 LR3 is a chain of 83 amino acids in length, it has the same complete sequence of IGF1 but with substitutions of an Arginine for the Glutamic Acid at position 3, hence Long R3. The variation in the sequence allows the IGF1 to avoid binding to porteinstherefore having a longer half-life. IGF1 LR3 has a molecular weight of 9.200 and its molecular formula is C990H1528N262O300S7. Along with possessing some fat metabolizing effects the modifications in LR3 increase transportation of glucose and amino acids to cells and stimulates protein generation. Research testing has shown it brings about muscle cell hyperplasia (new cells splitting and re-forming to make denser ones). IGF LR3 being more effective at this as a whole, it also may increase nitrogen retention and increase neuro-functions.
