What Is IGF-1 LR3?
IGF-1 LR3 (Long R3 IGF-1) is a modified analogue of insulin-like growth factor 1. An amino-acid substitution and a 13-residue N-terminal extension reduce its binding to IGF binding proteins and extend its activity relative to native IGF-1, making it a potent tool compound in cell-biology research.

How IGF-1 LR3 Is Studied to Work
In research IGF-1 LR3 acts at the IGF-1 receptor and is used to study growth-factor signalling, cell proliferation and differentiation in culture. Because it is a potent growth factor, it is handled as a specialised laboratory reagent.
Evidence, Safety & Regulatory Status
IGF-1 LR3 is not an approved medicine in the UK and is supplied for laboratory research only. As a growth factor it is also a prohibited substance in sport under World Anti-Doping Agency (WADA) rules. Potent signalling reagents of this type warrant careful, compliant laboratory handling.
Research Handling & Quality
As a lyophilised (freeze-dried) peptide it is typically stored frozen and reconstituted with bacteriostatic water for in-vitro work — see our reconstitution guide and storage guide. Identity and purity should be verified against a batch-matched Certificate of Analysis (COA) with HPLC and mass-spectrometry data. View igf-1-lr3 product details and COA.
