Application

IGF-1LR3 is a hormone with a molecular weight of 7.6kD and a molecular structure similar to insulin. 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.

Peptide Storage Guidelines: General Tips

When storing peptides, remember to:
• Store peptide in a cold, dry, dark place
• Avoid repeated freezing and thawing of peptide
• Avoid overexposure to the air
• Avoid light exposure
• Avoid storing peptides in solution long term

Peptides, as an organic compound, are formed by the dehydration of amino acids and play a variety of important roles in the human body. The following are the main benefits of peptides:
Nutritional supplementation: Peptides are high-quality nutrients that can be directly absorbed by the human body, providing the body with necessary amino acids, and are absorbed faster than ordinary proteins.
Promoting metabolism: Peptides participate in the body's metabolic process, can regulate enzyme activity in the body, and promote various chemical reactions. Strengthening muscles: Peptides can increase the uptake and utilization of amino acids in muscle cells, thereby promoting the synthesis and repair of muscle proteins. It can also stimulate the body to secrete growth hormone, thereby promoting muscle growth. Peptides also have many benefits such as regulating appetite, removing toxins from the body, improving sub-health conditions, relieving sexual dysfunction, and improving mental state. However, although peptides have many functions and effects, excessive supplementation may also lead to problems such as overnutrition and obesity. Therefore, in daily life, you should pay attention to supplementing peptides in moderation and avoid excessive intake. At the same time, when choosing peptide products, you should choose regular channels to purchase them and follow the instructions and dosage on the product manual.
In general, peptides, as an important bioactive substance, play an important role in promoting metabolism, enhancing immunity, promoting cell repair and regeneration, regulating physiological functions, etc., and have many positive effects on human health.

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).
