IGF-1 LR3: A Research Peptide Overview
Share
IGF-1 LR3 is a long-acting growth-factor analog widely used in cellular-proliferation research. This overview explains what it is, the pathways it's studied in, and how to source it.
What is IGF-1 LR3?
IGF-1 LR3 (Long Arg3 Insulin-like Growth Factor-1) is a modified version of IGF-1 engineered for a longer half-life and reduced binding to IGF-binding proteins. This makes it a stable, potent tool for receptor and cell-culture research.
Research pathways
- IGF-1-receptor signaling research.
- Cellular proliferation and protein-synthesis research models.
- Cell-culture and growth-factor research.
Formats & products
IGF-1 LR3 is supplied in lyophilized and pre-reconstituted activated forms: IGF-1 LR3 (1mg). It sits within the Anti-Aging & Longevity collection alongside growth-hormone secretagogues.
Handling, reconstitution & purity
Some growth factors are sensitive to solvent choice — confirm the appropriate solvent before reconstituting. See our reconstitution guide and the bacteriostatic water and acetic acid solution options. All material is ≥98% HPLC-verified, documented on the Quality & COA page.
Manufacturing & Quality
Alpha Biologix supplies IGF-1 LR3 under pharmaceutical-grade manufacturing standards, with each batch verified to ≥98% HPLC purity through independent third-party laboratory testing. A Certificate of Analysis (COA) is available per lot, giving researchers documented confirmation of identity and purity.
