Support Muscle Growth & Cellular Repair Pathways

IGF-1 LR3 (Insulin-Like Growth Factor-1 Long R3) is a modified form of IGF-1 engineered for extended biological activity. Structural modifications increase its resistance to binding proteins and enzymatic breakdown, allowing it to remain active longer than native IGF-1.

Through its involvement in cellular growth signaling and protein synthesis pathways, IGF-1 LR3 has been widely studied in research settings focused on muscle hypertrophy, tissue repair, recovery, and metabolic efficiency.

Product features
  • Long-acting IGF-1 analog — modified for extended half-life and enhanced activity.
  • Lyophilized (freeze-dried) formulation — supports stability and extended shelf life.
  • Sterile glass vial — packaged to maintain compound integrity.
  • Butyl rubber stopper — designed for secure, multi-access sealing.
  • Depyrogenated & tamper-evident flip cap — ensures research-grade quality control.
Key benefits (Research Highlights)
  • Muscle growth signaling — studied for promoting muscle cell proliferation, differentiation, and hypertrophy.
  • Protein synthesis & recovery — IGF-1 pathways are closely linked to muscle repair and reduced recovery time following mechanical stress.
  • Fat metabolism support — investigated for enhancing nutrient partitioning and fat utilization during recomposition research.
  • Endurance & performance pathways — cellular energy metabolism and tissue efficiency may support sustained physical output.
  • Anti-aging & regenerative interest — IGF-1 signaling is associated with cellular regeneration and maintenance of tissue integrity.
