BE A REAL HERO WITH REAL PEPTIDE IGF1-LR3

IGF1-LR3

IGF1-LR3 is a polypeptide hormone consisting of a chain of 70 amino acids in length. it is a nutrient shuttling hormone that is quite specific to muscle tissue, and it is an extremely anabolic hormone. It is also anabolic to bone, connective tissue, as well as intestinal tissues. IGF1-LR3 is the most common and very popular variant of IGF-1. It contains bio-identical IGF-1 consisting of the original 70-amino acid chain, but with an additional 13 amino acids at its N-terminus for a total of 83 amino acids. This product also possesses a second modification, where an arginine is located at the 3rd position rather than the original glutamic acid.

The result of these modifications is that the IGF-1 still exhibits its original activity at the IGF-1 receptor in body tissues, and has a very low binding affinity for the IGF binding proteins mentioned earlier. This product also exhibits a significantly extended half-life of approximately 20 – 30 hours as opposed to IGF-1’s 12 – 15-hour half-life. All of these factors combined have demonstrated LR3 to be about three times the potency of IGF-1.
