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.
