IGF-1 LR3

IGF-1 LR3 is a modified analogue of insulin-like growth factor-1 engineered with an extended amino acid sequence and reduced affinity for IGF-binding proteins relative to native IGF-1. It has been studied in growth and cellular signaling research for its relationship to anabolic pathways, cellular proliferation, tissue repair dynamics, and nutrient-partitioning behavior across experimental models.

IGF-1 LR3 is a modified analogue of insulin-like growth factor-1 engineered with an extended amino acid sequence and reduced affinity for IGF-binding proteins relative to native IGF-1. It has been studied in growth and cellular signaling research for its relationship to anabolic pathways, cellular proliferation, tissue repair dynamics, and nutrient-partitioning behavior across experimental models. Its LR3 modification substantially extends biological activity duration compared to endogenous IGF-1 structures. Lyophilized powder, 3mL vial. Sold at 1mg per vial. For research use only.
