"Steroid" is the name given to a chemical compound with a specific structure. In everyday speech, the term steroid is applied to several medications that share this structure; however, these medications have very different uses. Anabolic steroids are a class of drug that mimic the effects of male sex hormones called androgens which stimulate muscle growth and secondary male sex characteristics. They are often abused by bodybuilders and other athletes to build muscle mass and so should be used with caution. When prescribed, oral steroids should be taken as directed. If you come across extra pills that haven't been taken, and are unsure if they are steroids, you can identify the pill based on its physical appearance, information on the bottle, or by consulting a professional.
As an example, should you choose to run a cycle that includes both Dianabol and Anavar, you will need to be extremely careful when it comes to overlapping them. The two are both hepatotoxic, which means they will cause liver damage. You will need to consider this carefully when it comes to choosing cycle lengths. If you take Dianabol for four weeks at the beginning of your cycle, then make the switch to Anavar, you should limit your Anavar use to four weeks, as well. This reduces your entire cycle time to eight weeks, which helps to alleviate some of the risk of liver damage.
However, the Anavar steroid was discontinued by Searle in 1989, due to the bad press brought on by bodybuilders abusing the drug. It was later reintroduced to the world market as Oxandrin in 1995, but it remains a controlled substance under US law. The current manufacturer of oxandrolone holds all the rights to their medicine, and that’s why it is very rare to find oxandrolone today. It’s still called Anavar by most people, and it’s very hard to buy. Even if you do find Anavar for sale, the law of supply and demand inevitably results in a rather exorbitant price for the steroid.
