IGF-1 LR3

IGF-1 LR3 is a modified form of Insulin-Like Growth Factor-1 with an amino acid substitution and 13-amino acid N-terminal extension. These modifications reduce binding to IGF binding proteins, extending its half-life and bioavailability. Researchers study this compound for its enhanced anabolic signaling and cellular growth effects in laboratory models.

Scientific research on IGF-1 LR3 examines its effects on cellular proliferation, protein synthesis, and metabolic processes. Studies focus on its influence on muscle satellite cell activation, glucose uptake, protein degradation inhibition, and anabolic signaling pathways. Researchers investigate its mechanisms involving IGF-1 receptor activation, PI3K/Akt signaling, and mTOR pathway stimulation in experimental settings.
