Description
Buy Authentic IGF-1 LR3 1mg Online
IGF-1 LR3 1mg is a research-use-only laboratory material supplied for controlled research workflows, compound characterization, and analytical documentation review. It is manufactured under rigorous quality standards to support consistency, traceability, and batch-specific verification for qualified laboratory settings.
What IGF-1 LR3 1mg is:
IGF-1 LR3 = Insulin-like Growth Factor-1 Long Arg3. It’s a synthetic analog of human IGF-1 with 2 modifications: an arginine substituted at position 3, and a 13-amino-acid N-terminal extension. Those changes reduce binding to IGF-binding proteins and increase half-life vs native IGF-1. The “1mg” is the amount of lyophilized powder per vial. It’s sold strictly as a research peptide for laboratory studies, not for human or veterinary use.

IGF-1 LR3 1mg is intended strictly for laboratory research use only. This product is not intended for human or animal consumption, therapeutic use, diagnostic use, clinical use, veterinary use, or as a food, drug, cosmetic, dietary supplement, or household product.
How researchers study it*
: In cell culture and animal models, IGF-1 LR3 is used to investigate the IGF-1 receptor signaling pathway. Because it binds poorly to IGFBP-3 and other binding proteins, researchers use it to study prolonged IGF-1 receptor activation without the buffering effect of IGFBPs. Labs use it in models of cell growth, protein synthesis, glucose uptake, and tissue repair pathways.
Why it gets research attention
Native IGF-1 has a half-life of minutes due to rapid binding and clearance. LR3’s modifications give it a half-life of ∼20-30 hours in preclinical models. That lets researchers study sustained IGF-1 signaling with fewer doses. It’s used in vitro to model anabolic signaling cascades, satellite cell activation, and downstream mTOR/Akt pathways in controlled experiments.
Form, purity & handling
IGF-1 LR3 1mg is typically supplied as a white, freeze-dried powder in a sealed sterile vial. Reputable suppliers include a Certificate of Analysis with HPLC and mass spec to confirm sequence and purity, usually >95% for research grade. It’s extremely sensitive to heat, light, and moisture, and can adsorb to glass/plastic, so it’s shipped cold and stored at -20°C or -80°C after reconstitution. Acidic buffers are often used in labs
Legal + safety status
IGF-1 LR3 is not FDA-approved or approved by other major regulatory agencies for medical use. It’s classified “for research use only, not for human consumption.” Recombinant IGF-1 drugs like mecasermin exist for specific rare pediatric growth disorders, but LR3 is not an approved drug. It’s banned by WADA for athletes. It has no established human dose, safety profile, or pharmaceutical manufacturing standards.
Bottom line
*IGF-1 LR3 1mg* is a research tool used to study prolonged IGF-1 receptor activation in the lab. While IGF-1 biology is well-established, the LR3 analog itself has no approved medical use, clinical efficacy data, or human safety profile. For growth, metabolic, or recovery concerns, talk to a licensed healthcare provider about FDA-approved diagnostics and treatments with clinical data.
