High-risk, high-search growth factor often mislabeled as a simple ‘peptide’.
Also known as: Long R3 IGF-1 · IGF1 LR3
Part of the Growth hormone & IGF peptides cluster
Overview
IGF-1 LR3 is a long-acting analog of insulin-like growth factor-1 used in cell culture and experimental research. It is a potent growth factor and is not a casual research peptide.
Source & context
Biological / chemical source: Recombinant / synthetic analog
Primary research or clinical context: Research compound (potent growth factor; not for unregulated human use)
Not just another vial
IGF-axis molecules affect cell growth and metabolism broadly. Educational materials should stress laboratory biosafety, legal status, and the difference from short cosmetic or signaling peptides.
LR3 design
The Long R3 modification reduces binding to IGF-binding proteins and extends activity in experimental systems — a classic protein-engineering case study.
