 IGF-1 LR3, also known as Long Arginine 3-IGF-1, is a synthetic protein and a variant of insulin-like growth factor-1 (IGF-1). The difference between IGF-1 and IGF-1 LR3 is that the latter possesses an arginine instead of a glutamic acid at the third point of its amino acid sequence. It is also more potent and can be sustained in the body for over a day. IGF-1 LR3 peptide additionally inhibits the movement of glucose into the body cells to facilitate fat burning.


With the rise of medical innovation, research shows that IGF-1 LR3 is a potent and effective peptide with numerous abilities.


What is IGF1 LR3?


IGF-1 LR3 is a variant of IGF-1, a product of Growth Hormone that stimulates cell growth[i] throughout the body, enabling growth and development, tissue strengthening, increased bone density, and healing.


With a total of 83 amino acids, IGF-1 LR3 research peptide has an extremely low affinity for insulin-like growth factor-binding proteins and has shown rapid improvement in metabolic stability. It is thus considered to be three times more potent that IGF-1. The peptide also offers a much longer half-life of 20-30 hours[ii], whereas IGF-1 only has a half-life of 12-15 hours.




How Does IGF1 LR3 Work?


According to research, the main purpose of IGF-1 LR3 is to increase the biological activity of IGF. When the IGF-1 LR3 chemical is active in the body, it functions differently depending on the types of tissues. For example, IGF-1 LR3 used in muscle tissue would make the muscle more sensitive to the effects of insulin. On the other hand, while it has been proved to aid fat reduction, it could also cause fat increase due to muscle mass increase.


IGF1 is mainly associated with the human growth hormone, which maintains tissue health within the body. Produced in the liver, this long peptide is made possible by the pituitary gland – a tiny stricture at the base of the brain. Its role is primarily in the endocrine system to ensure hormone production and secretion run smoothly. It also regulates water levels in the body, signals milk production in pregnant women, and boosts the body’s metabolism. Besides that, IGF1 LR3 plays a role in sex hormone production and is an integral part of human growth.
