Therapeutic Interest Versus Bodybuilding and Performance Claims
Searches for IGF-1 LR3 often focus on muscle growth, muscle growth and recovery, body composition, or performance. The biological interest comes from the role of IGF-1 signaling in skeletal muscle protein synthesis, anabolism, and cell-growth pathways [12] [13

- Searches for IGF-1 LR3 often focus on muscle growth, muscle growth and recovery, body composition, or performance. The biological interest comes from the role of IGF-1 signaling in skeletal muscle protein synthesis, anabolism, and cell-growth pathways [12] [13].
- That does not make performance claims clinically proven. IGF-1 and its analogues are also prohibited in sport under WADA rules, which reflects anti-doping policy and safety concerns rather than evidence of safe or effective personal use [19].
