Introduction: Trenbolone acetate (brand name: Revalor) is a 19-nortestosterone derivative and a synthetic, injected anabolic-androgenic steroid that is used in veterinary medicine. It is a highly efficient anabolic steroid that can greatly enhance the performance of athletes. Trenbolone acetate has several physiological effects. First, it can greatly promote insulin-like growth factor-1 (IGF-1). IGF-1 is a powerful and natural anabolic hormone that of great importance for muscle tissue development. Secondly, it can greatly increase the red blood cell count, further increasing blood oxygen and enhancing muscular endurance. Moreover, it can inhibit the glucocorticoid hormone, a hormone that destroy muscle tissue and promote fat. Finally, it can improve nutrient uptake and consumption efficiency.
