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.
