Also be aware that
some sport supplements which are available (mostly over the internet) contain some substances which are more harmful than steroids, and
may make you fail a test. There are a lot of designer drugs out there marketed not as such. These are often (but not always) advertised as being ''more effective than steroids'', and work by artificially raising your testosterone level using twisted analogs of said substance which the liver cannot easilly break down. Taken over long periods they can even land people in A&E or the ER depending on what part of the world you are in. These come in respectable looking containers like everything else on sale and a lot of people dont even realise exactly the mechanisms of action of that which they are taking.
