IGF-1 LR3 (Long Arginine 3-IGF-1) is a modified insulin-like growth factor analogue with a reduced affinity for IGF-binding proteins, studied in growth and muscle research. It is supplied as a high-purity white lyophilized powder (>=99% HPLC) in sealed vials for laboratory use. IGF-1 LR3 is investigated in research on protein synthesis, cell growth and anabolic pathways, and is commonly applied in cell-culture and preclinical studies. The lyophilized format provides high stability and easy reconstitution for consistent experimental dosing. Every batch is quality-controlled to ensure reliable outcomes. Every batch undergoes strict quality control, and a Certificate of Analysis (COA) is available for specific batches upon request to support reproducible laboratory work. For storage, keep the unopened reagent sealed at 2-8 degree C and protected from light and moisture; for long-term storage, store at -20 degree C and avoid repeated freeze-thaw cycles. We support both small trial orders and large-volume bulk orders. OEM and private-label packaging services are available for research projects, and secure neutral packing is used for all shipments with worldwide delivery to the USA, Europe, Canada, Australia, the UK and many other regions.
