Oral Trenbolone is incredibly hepatotoxic, and even short cycles can take a toll. For this reason, most people prefer injectable Tren steroids. If you are interested in avoiding injections, though, and you want to use Tren oral, use the smallest possible dose that provides results for the shortest period possible. Be sure to also incorporate some liver protection into your cycle, whether you choose to use milk thistle or a specially-formulated liver care product. Overall, though, the consensus is that both oral and injectable Tren provide the same results at the same doses.
Because trenbolone acetate (often referred to as tren A) is a short-chain ester, it peaks more quickly than the enanthate version. Its much shorter half-life allows tren A's effects to dissipate after 2 to 3 days. Trenbolone enanthate ( tren E ), however, as a long-chain ester, is slower to peak and can take up to 2 to 3 weeks to lose its effects. Because tren E is slower to begin showing results, more patience is also called for. Tren A is often used during the last couple of weeks of a tren E bulking cycle, as it eases the transition to the recovery phase.
