A large amount of anabolic steroids were found, as well as other drugs that were supposed to be sold for a profit. The legal status of anabolic steroids varies from country to country. In the United States, anabolic steroids are listed as Schedule III controlled substances under the Controlled Substances Act, which makes possession of these substances without a prescription a federal offense punishable by up to seven years in prison.  In Canada, anabolic steroids and their derivatives are part of the Controlled Drugs and Substances Act and are Schedule IV substances, which means that it is illegal to receive or sell them without a prescription. However, possession is not punishable, a consequence reserved for substances in lists I, II or III. Those guilty of buying or selling anabolic steroids in Canada can be imprisoned for up to 18 months. The import or export of anabolic steroids is also accompanied by similar penalties.  Anabolic steroids are also illegal in Australia, Argentina, Brazil and Portugal without a prescription, and are listed as Schedule 4 controlled drugs in the United Kingdom. Arnold Schwarzenegger admitted to using anabolic steroids for many years during his bodybuilding career, although steroids were legal in the United States during the period he was using them.
 In 1997, he underwent surgery to correct a heart defect. Some have speculated that this is due to his use of anabolic steroids.  Although the use of anabolic steroids can sometimes lead to enlargement and thickening of the left ventricle, Schwarzenegger was born with a congenital genetic abnormality in which his heart had a bizuspid aortic valve, a condition that made its aortic valve with two instead of three spikes, which can sometimes cause problems later in life.  In the Netherlands, anabolic steroids are only available by prescription because of their serious side effects such as liver damage, kidney damage and thickening of the heart muscle. In the early 1970s, sports organizations, including the IOC and the ncAA, declared the use of anabolic steroids unethical, but without effective means to test athletes, the issue remained academic.  Dozens of Dutch-speaking websites sell steroids. « It would be good to try to curb this trade because it is now very easy to get and cheap at all, » Pim de Ronde, founder of the Netherlands` first outpatient steroid clinic, told NRC. Testosterone, the most active anabolic androgenic steroid produced by Leydig cells in the testicles, was first isolated in 1935 and chemically synthesized later that year. Synthetic testosterone derivatives quickly followed. At the end of the following decade, testosterone and its derivatives were used with varying degrees of success for a number of conditions. It wasn`t until the 1950s that athletes began to discover that anabolic steroids can increase their muscle mass. According to sports doctor John Ziegler, the first confirmed use of an anabolic steroid in an international sports competition took place at the weightlifting championships in Vienna in 1954, when Russian weightlifters used testosterone.
 The suspects are believed to have sold the banned steroids in a sports nutrition and supplement store without having a business license for them. The criminal network consisted mainly of Czech and Slovak nationals and was active in several countries. They coordinated their illegal activities from the Czech Republic and Slovakia, while the substances themselves were produced in Romania. The final products were repackaged in the Czech Republic and Slovakia and distributed by post to consumers in various other EU Member States such as Germany, Sweden and the Netherlands. The manufacture and sale of steroids and similar hormonal substances is illegal in the European Union because of the serious risks to public health they pose. Steroids are often used in fitness centers to produce muscle mass quickly and artificially, and are sold illegally to generate high profits for the criminal organizations responsible for distributing them. The Dutch Doping Authority expects that between 40,000 and 50,000 people in the Netherlands currently use anabolic steroids. « We are concerned that usage will continue to increase and the average user will become younger, » Herman Ram, director of the anti-doping authority, told the newspaper. Although it is illegal for human consumption, 2,4-dinitrophenol (DNP) remains available online and in some gyms.
DNP is widely used as a diet aid, has serious side effects and has been responsible for eight deaths in the UK since 2015. The Dutch authorities must do much more to curb the trade in anabolic steroids. These muscle enhancers are easily and cheaply available online, and tens of thousands of Dutch people use them, experts told NRC. The trade in anabolic steroids is also lucrative, as sellers have a slim chance of getting caught, according to the newspaper. The approach to the steroid trade is fragmented, with different authorities bearing some of the responsibility, but not the full picture. Earlier this year, the first conviction was handed down for the illegal sale of DNP for human consumption in the UK. In the late 1960s, Science published a study on the effects of Dianabol on athletes. This open study, conducted by J.P. O`Shea and colleagues at Oregon State University, confirmed the muscle-building effects of anabolic steroids on athletes who followed a high-protein diet.  Two years later, O`Shea replicated the results in a double-blind design.   Anabolic steroids are still widely used for veterinary purposes and often contain the same ingredients as those made for humans, but without the same quality control.
 These can also be dangerous as they may have been manufactured and handled in harsher and less sterile environments.  Often, these veterinary-grade anabolic steroids are used by athletes to circumvent restrictions in their home country. The administration of such risks carries great risks and users are often taken to the hospital with complications. Although different laws include the use of anabolic steroids in different jurisdictions, such illegal use underground is also discouraged by the online sports/steroid communities.  With the judicial support of Eurojust, the authorities of the Czech Republic, Slovakia and Romania took action against an organised criminal group (OCG) involved in the manufacture, distribution and sale of steroids and other illegal hormonal substances. During a day of action coordinated by Eurojust, a production site in Romania was seized and dismantled and more than 20 suspects were arrested. OCG`s estimated profit amounts to several million euros. In 1992, NFL football player Lyle Alzado died of a brain tumor that he said was caused by his steroid use.
 Although steroids are known to cause liver cancer, there is no published evidence that anabolic steroids cause either brain cancer or the specific type of T-cell lymphoma that caused Alzado`s death. However, Alzado also explained that he felt addicted to steroids and had become increasingly violent.   The use of anabolic steroids is prohibited by all major sports federations, including the International Olympic Committee, Major League Baseball, national football league, national basketball association, national hockey league, WWE, ICC, ITF, FIFA, World Rugby, FINA, UEFA, European Athletics Association and Brazilian Football Confederation. Anabolic steroids are controlled substances in many countries, including Argentina, Australia, Brazil, Canada, the Netherlands (NL), the United Kingdom (UK) and the United States (USA). Although DNP can be used safely and legally in biochemical research and chemical production, it is illegal for human consumption. However, due to its alleged fat-burning properties, the drug is still widely sold online and in gyms in the form of capsules or powders. In countries where anabolic steroids are illegal or controlled, the majority of steroids are purchased illegally through the black market trade.   These steroids are usually manufactured in other countries and therefore have to be smuggled across international borders.
