IGF-1 LR3 is a potent synthetic analog of insulin-like growth factor 1, featuring an arginine substitution at position three and an additional 13 amino acids at the N-terminus. These modifications make it significantly more potent and longer-lasting than native IGF-1, enhancing its effectiveness in stimulating cell growth, muscle repair, and metabolic activity. Researchers use IGF-1 LR3 in studies of tissue regeneration, lean mass development, fat metabolism, and endocrine signaling. Atomix Research supplies it in high purity, ensuring consistent and reliable performance in advanced laboratory settings.
