The most prominent side effect of turinabol is Oral Primobolan. Since it is a c17aa steroid, it presents certain liver toxicity. Even though it is not even nearly as toxic as Anadrol or Dianabol, it will still have an impact on liver function. Consequently, liver supporting ancillaries are a must during turinabol cycles, and cycle durations should be rather reduced no more than 6 weeks. Some people assure that turinabol is perfectly safe for the liver, and present the German athletes as the main argument for such claims. It is hard to deny that these athletes were administered with turinabol for a very long time, Oral Primobolan, and they did not have any major issues with their liver health. Hence, Primobolan pills liver checks should be done when taking tbol, and such liver supporting supplements as N2Guard must be taken. Another frequent side effect seen with anabolic steroids, are the stressed lipid levels.
