IGF-1 LR3 (Long Arg3 IGF-1) is a recombinant analog with two structural changes relative to native IGF-1: A glutamic acid to arginine substitution at position 3, which reduces IGFBP binding affinity

Product verification through lab testing reduces contamination risk and supports consistency

Plasma glutathione rose from 17 5 mol/l to 823 326 mol/l, and plasma cysteine increased from 8 9 mol/l to 114 45 mol/l

This way, it mirrors the original peptide image to maintain a similar 3D structure and binding properties, while also offering higher resistance to normal proteolytic enzymes, thereby extending its stability and half-life
