IGF-1 LR3 (Insulin-like Growth Factor-1 Long R3) is a synthetic analog of human IGF-1 that has been extensively studied in research for its role in cellular growth signaling pathways and protein synthesis mechanisms. This modified peptide variant contains an arginine substitution at position 3 and a 13-amino acid N-terminal extension, resulting in reduced binding affinity to IGF-binding proteins and extended half-life compared to native IGF-1.
Research investigations have focused on IGF-1 LR3’s interactions with IGF-1 receptors and its involvement in PI3K/Akt signaling cascades, mTOR pathway activation, and cellular proliferation processes. Laboratory studies have examined its effects on myoblast differentiation, satellite cell activation, and various metabolic pathways in controlled research environments.
Each 1mg vial of IGF-1 LR3 is supplied as a lyophilized powder for research use. This compound is sourced from the same supplier as our verified catalog, but the current batch has not yet completed Janoshik Analytical’s independent “Match-Batch” testing. Check current verification status at the Lab Results page.
