What it is
IGF-1 LR3 (Long R3 IGF-1) is a recombinant analog of insulin-like growth factor 1 with two modifications that extend half-life and reduce binding to IGF-binding proteins in research settings.
How it works
In research models, IGF-1 LR3 is studied as an IGF-1 receptor agonist with prolonged free-fraction activity in cell-culture research. Mechanistic research focuses on PI3K/AKT and MAPK pathways.
What researchers explore it for
Researchers have explored IGF-1 LR3 in cell-biology research, in protein-synthesis-pathway research, and as a standard reagent in cell-culture work.
Safety and interactions
IGF-1 LR3 is a high-potency research reagent — handling and storage in laboratory settings follow strict protocols. Banned for use in competitive sport by WADA. IGF-1 LR3 is for laboratory research use only and is not for human consumption. Not medical advice.
Research notes
Peptide family: IGF analogs. Frequently compared with IGF-1 DES. Standard cell-culture reagent. Lyophilized powder; reconstitution per laboratory protocols.
