It's all too tempting to take a literature reference citation after a given statement as meaning there is proof for the statement, but in popular literature, and it seems particularly in the nutritional supplement and steroid-writing fields, that all too often is not the case. Quite often only a small part of the statement is backed up, or would be backed up except there is a misapplication, or even in many cases with regard to nutritional supplements one often sees references given in advertisements that aren't even tangentially related to the claim. But people see the reference and assume, Oh, it must be true.
It was in late 2005 that the status of methasterone, in addition to that of four other designer steroids, as an AAS was brought to public awareness by an article published in the Washington Post .  Don Catlin of the UCLA Olympic Laboratory, who conducted the studies, noted methasterone’s similarity to drostanolone. A warning by the FDA was issued soon after to the general public as well as to the distributor, Designer Supplements LLC, for the marketing of this compound.  Methasterone was subsequently added to the World Anti-Doping Agency (WADA) list of prohibited substances in sport.  Despite all of this, methasterone has resurfaced within the supplement industry on several occasions since its banning by WADA.
