IGF-1-LR3 1mg

IGF-1-LR3 1mg

IGF-1 LR3 is a long-acting analogue of insulin-like growth factor 1, engineered to resist binding proteins and remain active for extended periods. It is widely studied for its role in cellular growth, muscle development, and tissue-regeneration pathways. This peptide has ideal research in these categories:

  1. – Muscle Growth & Performance
  2. – Tissue Repair
  3. – Metabolic Enhancement

Understanding This Peptide

LR3 stands for “Long Arg3,” referencing the substitution that increases IGF-1’s half-life and reduces its affinity for IGF-binding proteins. This allows researchers to explore IGF-1 activity more directly and consistently across studies focused on growth, repair, and metabolism.

Mechanism of Action

IGF-1 LR3 binds to IGF-1 receptors and insulin receptors, promoting cellular growth, nutrient uptake, and protein synthesis. Its extended activity window provides a more sustained environment for examining anabolic and regenerative pathways.

Scientific Interest

Researchers turn to IGF-1 LR3 for its anabolic profile and its central role in GH/IGF-1 signaling. It is especially valuable in studies exploring muscle growth, recovery, and tissue repair.

Research Focus & Clinical Landscape

Active areas of investigation include:

  1. – muscle-protein synthesis
  2. – muscle-cell proliferation
  3. – tissue repair
  4. – nutrient uptake
  5. – metabolic regulation
  6. – GH/IGF-1 axis studies

IGF-1 LR3 is widely used across both performance physiology and tissue-regeneration research models.

Quality, Craftsmanship & Purity

Manufactured at >98% purity under GMP-aligned standards, IGF-1 LR3 undergoes rigorous testing for identity, potency, and consistency.

Final Insight

IGF-1 LR3 offers a powerful, extended-activity model for studying growth, repair, and metabolic pathways central to human physiology.
