IGF-1 LR3 (Long R3 Insulin Like Growth Factor 1) is a modified analog of IGF-1 engineered to extend half life and reduce binding to IGF binding proteins (IGFBPs). This design is discussed as increasing bioavailability and prolonging IGF-1 receptor signaling compared with native IGF-1, which is why it is often studied in anabolic, recovery, and tissue repair research contexts.
Available Formats
- 1mg lyophilized peptide
Mechanism of Action
- Bind IGF-1 receptors, driving anabolic and repair related signaling across muscle and connective tissue models
- Reduce IGFBP binding, increasing free fraction availability and extending duration of effect
- Increase protein synthesis signaling and support muscle hypertrophy endpoints
- Extend the anabolic window by maintaining IGF-1 receptor activation over a longer exposure period
Areas of Investigation
IGF-1 LR3 is commonly studied for
- Lean mass and muscle growth related endpoints through sustained anabolic signaling
- Faster recovery signals and improved tissue repair related outcomes in some models
- Body composition improvements through increased lipolysis signals while preserving lean tissue
- Connective tissue and joint support endpoints relevant to injury recovery paradigms
Interaction Notes
- Commonly studied with PEG-MGF for muscle-repair synergy
- Sometimes paired with GH secretagogues in growth-related research
- May interact with insulin pathways -\> researchers monitor glucose markers
- No negative interactions documented between IGF-1 LR3 and other peptides in controlled studies
