IGF-1 LR3, is also called Long arginine 3-IGF-1, is a synthetic protein and lengthened analogue of human insulin-like growth factor 1 (IGF-1). It can be found in human, to increase Insulin binding protein and stimulate more growth hormone. So it benefits in building lean muscles and losing fat.
Comparing with HGH, the effect of IGF-1 LR3 is faster and more directly. IGF-I regulates the anabolic effects of GH. It goes to the muscles and ligaments where it develops lean tissue. By traveling to the fat cells, IGF-I burns fat. Subsequently, it increases lean body mass and decreases fat—the two most wanted effects by athletes, particularly bodybuilders. In addition to a direct anabolic effect on skeletal muscle—for example, the production of more protein—IGF-I is also capable of stimulating the proliferation and differentiation of muscle stem cells (satellite cells).
IGF-1 lr3 has been applied in many field:
(1) in phamaceutical field, it is used as phamaceutical raw material to treat injuries from fall, infectious hepatitis and
epidemic cerebrospinal meningitis.
(2) in healthcare field, it is used in the health products to nourish brain, protect liver and improve sleep quality.
(3) in comestics, it is used to promote skin metabolism and make skin more tender and firm.
