IGF-1 LR3 is an extended-acting analog of insulin-like growth factor 1. It is studied for its role in muscle growth, tissue repair, and cellular regeneration.
LR3 has a longer half-life than native IGF-1, allowing it to interact with cellular pathways that support protein synthesis, recovery, and structural tissue development.
Key Highlights:
• Supports muscle growth & repair
• Encourages protein synthesis
• Enhances cellular regeneration
• Longer activity window than IGF-1
• Common in performance & recovery studies
