IGF-1 LR3 is a synthetic analog of insulin-like growth factor-1 (IGF-1), modified to resist degradation and extend its half-life to 20–30 hours. It binds to the IGF-1 receptor, activating PI3K/Akt/mTOR and MAPK/ERK pathways to stimulate protein synthesis, muscle cell proliferation, and satellite cell activation.

It promotes muscle growth (hypertrophy and hyperplasia), fat loss, and tissue repair, while enhancing glucose and amino acid uptake into muscle cells. Due to reduced binding to IGF-binding proteins (IGFBPs), it remains biologically active longer than native IGF-1, making it more potent in research settings.
