Injectable steroids are not harmful to the liver. The main and biggest plus of the anabolic drugs that are available in the form of solutions is their safety. Almost all oral steroids produced in capsules and tablets have a negative effect on the liver (and some on the kidneys), especially when used improperly, in large doses. Some can cause stomach and intestinal problems, such as gastritis. Solutions for injection do not have this negative effect. After all, when you inject the solution into the muscle, it begins to be absorbed directly into the blood, bypassing the liver exert their effect faster.
