Injectable Steroids are considered to be those types of anabolic steroids that are oil based or water based.  Injectables are usually injected directly into the muscle, not into the vein, in other words they should be taken intramuscularly. Intramuscular injections are ususally used when prompt absorption is desired, when larger doses are needed than can be given cutaneously or when a drug is too irritating to be given subcutaneously.

Taking into consideration that injectable steroids last longer (they have esters which make them longer-acting) and that they are not so liver toxic, bodybuilders and athletes often prefer their usage.

Injection steroids have not so many side effects compared to oral steroids since they are chemically designed to bypass the digestive system. They do not possess the 17 alpha alkylation of most oral steroids, thus they are considered to have less health risks than their oral counterparts.

When using injectables it is necessary to remember to inject them into the muscle tissues, also to sanitize syringes, injection sites, vials, etc. in order to prevent the infection from occurring. It is also important to choose the proper syringe for the administration of injectable anabolic steroids.
