Trenabol(trenbolone enanthate) is an injectable form of the strong anabolic steroid trenbolone. Given the use of an enanthate ester, this drug will exhibit virtually identical pharmacokinetics to testosterone enanthate, providing a peak release of its steroid within the first several days after injection, followed by declining levels for approximately 2 weeks. The base steroid here (trenbolone) is a derivative of nandrolone, and exhibits strong anabolic and androgenic properties. On a milligram for milligram basis it is considerably more potent than testosterone as both an anabolic and androgenic agent, though it does carry a more favorable balance (toward anabolism). Trenbolone is also unable to convert to estrogen, however it does exhibit notable progestational activity, which may mimic estrogenic side effects given the right physiological conditions. Trenbolone enanthate is virtually interchangeable with Parabolan (trenbolone hexahydrobenzylcarbonate), capable of promoting strong gains in lean muscle mass, often with an accompanying increase in relative hardness and definition.
Trenbolone enanthate was never approved for use in humans. Prescribing guidelines are unavailable. Common doses for physique- and performance-enhancing purposes fall in the range of 150-300 mg per week, which is usually taken for 6-10 consecutive weeks. This level is sufficient to produce considerable increases in lean muscle mass and strength, which are usually combined with notable fat loss and increased muscle definition. As with all trenbolone injectables, this product is fairly versatile, and can be combined with many other agents depending on the desired results.
