 IGF-1 LR3 (insulin-like growth factor-1 long arginine 3) is a synthetic, modified construct of insulin-like growth factor-1. Because IGF-1 LR3 does not bind to IGF-1 binding proteins very well, it remains active up to 120 times longer than standard IGF-1. This results in improved half-life for the peptide and thus increased activity. IGF-1 LR3 enhances cell division and growth, boosts fat metabolism, and increases muscle repair and hypertrophy by inhibiting myostatin. Recent research suggests that IGF-1 LR3 may also be useful in improving lactation among mothers with young offspring.



IGF-1 is a peptide consisting of 70 amino acids with a molecular weight of 7649 Da. IGF-1 has an A and B chain connected by disulfide bonds, like insulin, which is how it gets its name. The structural similarity to insulin explains the ability of IGF-1 to bind (with low affinity) to the insulin receptor. IGF-1 is secreted by many tissues and the secretory site seems to determine its actions. Most IGF-1 is secreted by the liver and is transported to other tissues, acting as an endocrine hormone. IGF-1 is also secreted by other tissues, including cartilaginous cells, and acts locally as a paracrine hormone.

Most of the IGF-1 produced by the liver is secreted for its proliferative and growth effects. Lower IGF-1 and growth hormone are often associated with excess body fat. IGF-1 and other proteins in the IGF family are growth factors that stimulate the proliferation and survival of various cell types including muscle, bone, and cartilage tissue. IGF-1 plays an important role in childhood growth and continues to have anabolic effects in adults. A synthetic analog of IGF-1, mecasermin is commercially available and is used for the treatment of growth failure. Therapeutic administration of IGF-1 is associated with reversing insulin sensitivity, reducing weight, and increasing metabolic expenditure as well as potential reversal of degeneration of spinal cord motor neuron axons in certain peripheral neuropathies.

IGF-1 LR3 has a modified amino acid sequence compared to biological IGF-1. It has an additional arginine at amino acid position 2. By making this change, it gives the molecule higher potency and a much longer half-life. For this reason, it is commonly used as a long-acting version for the same therapeutic reasons as the IGF-1.


IGF-1 LR3 is primarily used to increase the biological activity of IGF. When IGF-1 LR3 is mobile in the body, it functions differently in individual types of tissues. For example, in muscle tissue, it forces the muscle to be more sensitive to insulin's effects, such as the decrease of fat storage.

IGF-1 LR3 is recommended to patients with the following conditions: hormone deficiency in children that results in short stature, adult growth deficiency, short bowel syndrome, short stature due to Turner Syndrome, adult deficiency associated with pituitary tumors or treatment of these tumors and muscle-wasting disease related to HIV/AIDS.

 What are the Benefits of IGF1-LR3?

Based on the literature, IGF1-LR3 has been shown to:

  • Increase Fat Loss
  • Aid in the development of lean muscle mass
  • Add protection against muscle wasting
  • Reduce inflammation
