If you can do these things, if you can supplement with responsible doses for responsible periods of time; if you can avoid OTC meds where possible as well as alcohol consumption your liver will remain healthy. If you do these things, your liver enzyme values will increase with oral steroid use, but if your liver was healthy to begin with the enzyme values will return to normal shortly after oral use is discontinued as the liver possess remarkable rejuvenating capabilities. There is one more important note we must mention; all steroid stacking plans that include oral anabolic steroids should extend past oral use if gains are to be maintained. Further, if it’s a long cycle that includes oral steroids at two different points there should be at least 4 weeks of no oral use between the two phases. This last note on the 4 week break is not something most will need to concern themselves with, as the only ones who it will affect are the extremely hardcore who run very long cycles.

Each user experiences their own unique feelings when using steroids and coming off the drug. When someone chooses to stop using they can experience a variety of withdrawal symptoms linked to addiction. Symptoms can include mood swings, fatigue, restlessness, loss of appetite, insomnia, reduced sex drive, the desire to take more steroids, and depression. Evidence for steroid addiction is certainly not as strong as it is for other drugs like cocaine or heroin. Though it is clear that people develop a tolerance and dependence on them and willingly experience negative consequences when using steroids - both of which are signs for drug dependence.
