What IGF-1 LR3 is
A long-acting analogue of IGF-1 studied in animal models for muscle growth and tissue repair.
IGF-1 LR3 is a modified version of insulin-like growth factor 1 with an arginine substitution and an N-terminal extension that reduce binding to IGF-binding proteins, extending its half-life to roughly a day. It is studied in animal models for muscle protein synthesis and repair.
Mechanism: Activates the IGF-1 receptor, driving cellular growth, proliferation, and protein synthesis; reduced binding-protein affinity prolongs activity.
Regulatory history: Not FDA-approved
