I have had a series of both facet block injections and steroid epidurals with my most recent one in August, 2012. I have degenerative disc/spondylolisthesis at L4/5 diagnosed years ago. I am very fit and worked hard most of my life to eat healthy, exercise at an intense level, and keep my weight in normal range. Facet blocks and steroid epidurals will make you gain weight and even though I've continued to exercise and watch my diet throughout my treatments, I have still gained 10-15 lbs.
Some prescriptions like Lyrica will also make you gain wieght very quickly.
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.
