What Is IGF-1 LR3 1MG?

IGF-1 LR3 (Long Arginine 3-IGF-1) is a synthetic analog of human insulin-like growth factor 1 (IGF-1). It is an 83-amino acid peptide with a molecular weight of 9117.60 g/mol. IGF-1 LR3 differs from native IGF-1 by the substitution of an arginine for glutamic acid at position 3 and the addition of a 13-amino acid extension at the N-terminus. These modifications result in significantly reduced binding to IGF binding proteins, increased biological potency, and extended half-life compared to native IGF-1

Structure

Research Findings

Enhanced Potency: IGF-1 LR3 has been shown to be approximately three times more potent than native IGF-1 in stimulating cell proliferation and survival.
Increased Half-life: The half-life of IGF-1 LR3 is significantly longer (20-30 hours) compared to native IGF-1 (12-15 hours), allowing for less frequent dosing.
Muscle Growth: Studies have demonstrated that IGF-1 LR3 can promote muscle cell proliferation and hypertrophy, making it of interest in treating muscle-wasting conditions.
Reduced IGFBP Binding: IGF-1 LR3 has very low affinity for IGF binding proteins, which allows for greater bioavailability and enhanced biological activity.
Fetal Growth: Research in animal models has shown that IGF-1 LR3 can promote organ-specific growth in fetuses, potentially offering therapeutic applications for intrauterine growth restriction.

Future Research Directions

Clinical Applications: Further research is needed to explore the potential therapeutic uses of IGF-1 LR3 in conditions such as growth hormone deficiency, muscle-wasting diseases, and intrauterine growth restriction.
Long-term Safety: Extended studies are required to evaluate the long-term effects and safety profile of IGF-1 LR3, particularly in diverse patient populations.
Delivery Methods: Investigation into optimal delivery methods and dosing regimens for different conditions could enhance the therapeutic potential of IGF-1 LR3.
Combination Therapies: Exploring potential synergistic effects of IGF-1 LR3 with other growth factors or therapeutic agents could open new avenues for treatment in various medical fields.
Mechanism of Action: Further research is needed to fully elucidate the molecular mechanisms by which IGF-1 LR3 exerts its diverse effects across different tissue types.
