IGF-1 LR3 | 1mg

1mg lyophilized IGF-1 LR3

IGF-1 LR3 (Insulin-Like Growth Factor-1 Long Arg3) is a synthetic peptide analog of IGF-1, designed to extend its half-life and enhance its biological activity. IGF-1, a hormone similar in molecular structure to insulin, plays a crucial role in growth and development, especially during childhood. It continues to exert anabolic effects in adults, contributing to muscle growth, repair, and overall cellular health.

Molecular Structure and Mechanism of Action:

IGF-1 LR3 is modified at the third position of its amino acid sequence, replacing glutamic acid with arginine (Arg3), and has an additional 13 amino acid extension at the N-terminus. These modifications significantly increase its half-life from approximately 20 minutes to over 20 hours, enhancing its stability and reducing the frequency of administration required.

The primary mechanism of action involves binding to IGF-1 receptors on the surface of cells, activating intracellular signaling pathways such as the PI3K/Akt and MAPK pathways. This activation promotes protein synthesis, cellular growth, and differentiation, contributing to muscle hypertrophy and enhanced recovery processes.

Research Findings:

Muscle Growth and Hypertrophy: Studies have demonstrated that IGF-1 LR3 significantly enhances muscle growth by stimulating myoblast proliferation and differentiation. Its prolonged activity results in sustained anabolic effects, making it a valuable tool for investigating muscle development and regeneration.

Tissue Repair and Regeneration: IGF-1 LR3 has been shown to accelerate tissue repair and regeneration, particularly in skeletal muscle, tendons, and ligaments. Research indicates its potential in treating muscle wasting conditions and injuries, promoting faster recovery and improved functional outcomes.

Neuroprotection: Emerging evidence suggests that IGF-1 LR3 may have neuroprotective properties. It has been observed to support neuronal survival, differentiation, and synaptic plasticity, highlighting its potential therapeutic applications in neurodegenerative diseases and brain injury recovery.

Metabolic Effects: IGF-1 LR3 influences metabolic processes, including glucose metabolism and lipid utilization. Studies have shown that it can enhance insulin sensitivity and promote fat loss by increasing the oxidation of fatty acids, suggesting potential benefits in metabolic disorders.

Longevity and Aging: Research into the effects of IGF-1 LR3 on aging and longevity is ongoing. Preliminary findings indicate that modulating IGF-1 signaling pathways can impact the aging process, with potential implications for age-related diseases and overall lifespan.

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

IGF-1 LR3 works by binding to the IGF-1 receptor on muscle cells, which activates a signaling pathway that promotes protein synthesis and inhibits protein breakdown. This leads to an increase in muscle mass and strength over time.
