    ———— Product Application ————



    IGF-1LR3 is a hormone with a molecular weight of 7.6kD and a molecular structure similar to . The main mechanism of action is to induce intracellular signal transduction by binding to its specific receptor (IGF1R). IGF-1LR3 is one of the most effective activators of the AKT signaling pathway. After activating the AKT signaling pathway, it stimulates cell growth and proliferation and inhibits cell apoptosis. IGF-1LR3 adds 13 amino acids to the N-terminus of the complete IGF-1 molecule to form an 83-amino acid long-chain IGF-1, and replaces the third amino acid glutamic acid (E) of the IGF-1 molecule with arginine (R), so it is called R3. Compared with unmodified IGF-1, IGF-1LR3 has higher stability and biological activity.


    Function
    1.Increase Fat Loss.
    2.Aid in the development of lean muscle mass.
    3.Add protection against muscle wasting.
    4.Reduce inflammation.

    ECHEMI Editorial Reference
    Long arginine 3-IGF-1, abbreviated as IGF-1 LR3 or LR3-IGF-1, is a synthetic protein and lengthened analogue of human insulin-like growth factor 1 (IGF-1). It differs from native IGF-1 in that it possesses an arginine instead of a glutamic acid at the third position in its amino acid sequence ("arginine 3"), and also has an additional 13 amino acids at its N-terminus (MFPAMPLLSLFVN) ("long"), for a total of 83 amino acids (relative to the 70 of IGF-1).
