IGF 1 – LR3

IGF-1 LR3 – Advanced Growth Factor Research Peptide

For Professional Research Use Only

IGF-1 LR3 (Insulin-Like Growth Factor-1 Long Arg³) is a modified analogue of endogenous IGF-1, engineered to extend half-life and enhance receptor activity. It is widely studied for its role in cellular growth, tissue regeneration, and metabolic signalling.

IGF-1 LR3 is a foundational compound in growth factor and anabolic signalling research, valued for its potency and prolonged biological activity.

What Is IGF-1 LR3?

IGF-1 LR3 is a recombinant peptide consisting of 83 amino acids, featuring an arginine substitution and an extended peptide chain that significantly reduces binding to IGF-binding proteins.

These modifications result in:

• Prolonged circulation time

• Enhanced receptor interaction

• Increased biological availability in research models

Compared to native IGF-1, IGF-1 LR3 offers greater stability and sustained activity, making it ideal for controlled laboratory research.

Key Research Applications

IGF-1 LR3 is commonly studied for its potential role in:

• Cellular proliferation and differentiation research

• Muscle growth and repair models

• Satellite cell activation studies

• Tissue regeneration and recovery research

• Nutrient partitioning and metabolic signalling

• Anti-catabolic pathway investigation

Its potent signalling effects make IGF-1 LR3 central to growth-related and regenerative research protocols.

Mechanism of Action

IGF-1 LR3 binds to IGF-1 receptors, activating intracellular signalling pathways responsible for:

• Cell growth and replication

• Protein synthesis enhancement

• Inhibition of protein breakdown

• Tissue repair and regeneration

By maintaining prolonged receptor engagement, IGF-1 LR3 enables sustained anabolic signalling in research environments.
