Non-medical users of anabolic steroids often “stack” different anabolic steroids over the course of a “cycle” of use. They also administer various ancillary drugs and substances to enhance the desired effects of anabolic steroids or to minimize adverse side effects. The most common liquid (injectable) anabolic steroids encountered in these cases are (oil-based) esters of testosterone (., testosterone cypionate, testosterone enanthate, and testosterone propionate, and a blend of testosterone esters called Sustanon 250) or nandrolone (., nandrolone decanoate). Also popular are Equipoise (boldenone undecylenate) and trenbolone acetate and trenbolone enanthate, as well as the water-based injectable Winstrol (stanozolol). Popular oral anabolic steroids include methandrostenolone (Dianbol), oxandrolone (Anavar) and oxymetholone (Anadrol 50).
The most obvious benefit that injectable steroids have over their oral cousins is that they are not hepatotoxic. Injectable steroids are safer on the liver and the user does not risk hepatic injury because injectable compounds don’t require specific chemical alterations which allow them to survive passing through the liver without being broken almost entirely down. It’s also worth consider that injectable steroids have a much longer half-life due to the ester attached to the hormone. To get the maximum benefit from oral steroids, most must be administered daily, or sometimes they are spread out throughout the day. The ester present in injectable steroids allows a much more infrequent administration and don’t need to be administered daily. More information about Esters
