IGF-1 LR3 (Long R3 IGF-1) is a modified, longer-acting analog of insulin-like growth factor 1. It is studied in cell and growth research and supplied for research use only.
What IGF-1 LR3 is
IGF-1 is a naturally occurring growth factor. IGF-1 LR3 is an engineered version, modified so it is longer-acting than the natural molecule. The name reflects those modifications: Long R3. It is a larger peptide than most in this library.
How it is studied
In the laboratory, IGF-1 LR3 is studied in cell and growth research. As a research peptide, it is a study tool and is not approved or intended for human use.
What to look for
A research-grade IGF-1 LR3 should ship with a batch-specific certificate of analysis confirming purity and identity.
Key takeaways
- IGF-1 LR3 is a modified, longer-acting analog of IGF-1.
- The name Long R3 reflects the modifications that extend its action.
- It is studied in cell and growth research.
- Research-grade IGF-1 LR3 is supplied for research use only.
A note on research use
The peptides supplied by Axis Peptide Labs are reference compounds for laboratory and research use only. They are intended for qualified researchers working in academic, institutional, and analytical settings. They are not drugs, foods, cosmetics, or medical products, and they are not intended for human or veterinary consumption. Documented identity and documented purity are what matter most when sourcing a compound, both of which are published on the Axis certificates of analysis page.
