IGF-1 LR3 (Long Arginine 3-IGF-1) is a recombinant analogue of insulin-like growth factor-1 engineered with an extended N-terminus that reduces binding to IGF-binding proteins, studied in growth research. It is supplied as a high-purity white lyophilized powder at >=99% HPLC purity in sealed vials. IGF-1 LR3 is investigated in research on protein synthesis, cell growth and anabolic signaling, and is commonly applied in cell-culture and preclinical studies. The lyophilized format provides stable reconstitution and consistent dosing. IGF-1 LR3 is the long-acting analog investigators reach for when a growth-factor study needs prolonged receptor engagement, and it is usually compared against native IGF-1 in proliferation, differentiation and in vivo growth models. Because dosing windows extend over days, the lyophilized presentation supports accurate reconstitution and repeat administration, and each batch record lets labs state the exact specification used. We supply matched vials from a single lot for cohort designs, and packing is arranged to preserve the peptide during transit. The long-acting analog dissolves in the indicated buffer volume, and our notes cover storage for both powder and prepared aliquots across multi-day dosing. Cohort designs benefit from matched vials, and we can reserve one lot for the full culture program. Bulk supply and custom vial sizes are available, with delivery arranged within recommended conditions. Orders are processed promptly after confirmation, with professional packaging that protects lyophilized material during transit. We support both trial quantities for evaluation and bulk volumes for ongoing research programs, with dedicated after-sales assistance at every step.
