IGF-1 (Insulin-Like Growth Factor-1) is a naturally occurring peptide hormone extensively studied for its involvement in cellular growth, tissue development, protein metabolism, and physiological regulation. It serves as an important mediator of growth hormone–related signaling and plays a role in pathways associated with cellular proliferation, differentiation, and tissue maintenance. Scientific research has examined IGF-1 in relation to muscle biology, metabolic regulation, tissue remodeling, and recovery-related mechanisms.Within exercise and performance research, IGF-1 is investigated for its potential relationship with muscle adaptation, protein synthesis, tissue recovery, and responses to physical training. Researchers continue to evaluate its molecular signaling, biological activity, pharmacokinetic characteristics, and broader physiological effects. Further controlled research is necessary to establish specific applications, safety, and long-term outcomes.
