Why can’t people trust some journalists that write about steroids?

Since subjects linked with steroids are widely read around the world, a lot of reporters present them even without appropriate knowledge related to these substances. Some reporters are not able even spell names of the products about which they write articles. In case an article’s subject is about a popular steroid taken by various athletes, readers expect to find out about important features and studies connected with this steroid. A journalist who writes about a steroid has to know at least general information connected with it.
Unluckily, you may come across significant lack of knowledge, when you read pieces of news connected with steroids. For example, the reporter Matthew Kelly has written an article about Nandrolone Decanoate which was published in the Newcastle Herald newspaper. It is known that the trade name of this medicine is quite popular. Athletes frequently call it shortly: they name it just Deca instead of Deca Durabolin.  The name  “Deca Durabolin” has been applied for over 50 years. But the reporter of the Newcastle Herald has done mistakes even in the name of this well-known steroid. This journalist has written it following: Decca Duarbulon. Could you trust this reporter? Could you be sure that the other statements which are presented by this reporter  are correct, if he can’t even write the name of the medication correctly? Moreover, it is not the only example of ignorance  about the things he writes. The Newcastle Herald seems to lack studies related to steroids. Kelly asks the local trainer to support his confirmation about steroids that is following: black market of anabolic steroids is full of young sportsmen that look for drugs that have performance-enhancing effects to build muscled bodies. Since it must be true, the trainer can’t support the affirmation because he knows just the aspects he has been said. He can’t report anything really because he is not involved in this problem directly.
Another lack of researches is shown in the Newcastle Herald’s description of the methods to detect users of steroids. It is written that if a person has muscled arms but not chest or  a massive chest and not arms, he\she is steroid user. This is the “depth” of studies presented by the Newcastle Herald.
