Factory Direct IGF-1 LR3 | Full COA | Professional Service & Fast Shipping

IGF‑1 LR3 (Long R3‑Insulin‑like Growth Factor‑1) is a synthetic, long‑acting analog of native human Insulin‑like Growth Factor‑1, engineered with an arginine substitution at position 3 and a 13‑amino acid N‑terminal extension. These structural modifications drastically reduce binding to IGF‑binding proteins (IGFBPs), extend its half‑life to approximately 20–30 hours, and boost bioavailability and biological potency up to 3× higher than native IGF‑1. It is widely used in cutting‑edge biomedical research, including cell proliferation, muscle hypertrophy, tissue repair, metabolism regulation, cell culture studies, and regenerative medicine models.

Our IGF‑1 LR3 is manufactured using advanced solid‑phase peptide synthesis under strict quality control and standardized production processes. Every batch is rigorously tested via High‑Performance Liquid Chromatography (HPLC) to ensure purity ≥98%, with a complete Certificate of Analysis (COA) provided for full quality traceability. The product is supplied as white to off‑white lyophilized powder, which delivers excellent stability, low moisture content, and strong resistance to degradation during long‑term storage and international transportation. It features good solubility and easy reconstitution, allowing researchers to prepare solutions of precise concentrations for various experimental applications.

We have been engaged in the research and supply of high‑grade peptide products for many years, adhering to the principles of Quality First, Service Supreme, Customer Foremost. We have established a complete quality assurance system, professional logistics solutions, efficient pre‑sales consultation, and thoughtful after‑sales support. From order confirmation, secure packaging, and fast shipping to after‑sales tracking and technical guidance, we provide customers with a one‑stop, full‑process service to ensure a safe, smooth, and satisfying experience.

Over the years, our IGF‑1 LR3 has been exported to numerous countries and regions including Europe, America, Southeast Asia, Oceania, and the Middle East.
