COA Included

IGF-1 LR3 (Long R3 Insulin-like Growth Factor-1) is a synthetic analogue of IGF-1 with an 83 amino acid sequence including a 13 amino acid extension at the N-terminus and a glutamic acid substitution. These modifications reduce binding to IGF binding proteins, extending its biological half-life to approximately 20-30 hours compared to native IGF-1's 15-minute half-life.

  • Extended half-life: ~20-30 hours vs 15 min for native IGF-1
  • Reduced IGF binding protein affinity
  • Potent activation of IGF-1R signalling pathway
  • Investigated in skeletal muscle and anabolic biology
  • 1mg lyophilised vial — research grade
