Testosterone propionate is very effective when it comes to rapid growth of muscle mass and strength. When using propionate, side effects are much less pronounced than when using enanthate. Perhaps this is due to the fact that he does not achieve such high blood values as enanthat. It is also distinguished from enanthate by a much lower retention of water and minerals in the body and a lower risk of gynecomastia. The mass made on propionate is more "dry" and the muscles more clearly defined.
