Do college athletes use steroids?

A few college athletes are caught applying prohibited drugs. Does it mean that they don’t take performance-enhancing drugs? Less than 1% of college football players have been caught violating anti-doping rules. They have tested positive for anabolic steroids and/or other performance-enhancing drugs. Such situation must convince anti-doping agencies that they win in the war on doping. But several suspicions arise. It is believed that numerous college football players take steroids and/or other related medications but they avoid detection successfully.
Why do such suspicions arise? Changes in appearance of college football players lead to controversial opinions. So, changes in body weight of over 61,000 college football players were recently analyzed by the Associated Press. Results displayed that numerous college football players enhanced their body mass in short period of time significantly. More than 20 pounds were gained by more than 4,500 college football players during a year. Moreover, circa 100 persons increased the body mass by more than 80 pounds during a year. As you see, the gains were significant.
Certain specialists assure that these aspects should not trouble anti-doping officers. They affirm that anti-doping officers shouldn’t subject college football players to drug tests just because they have increased body weight essentially.
But other specialists have another point of view. However they agree that it is impossible to be sure that certain football players have applied steroids and/or other related medications, basing only on changes in body weight, they notice that the changes may be a factor that causes suspicions connected with administration of steroids. So, such persons that have increased body weight in short time should be subjected to drug testing.
Certain college athletes that enhanced body mass essentially in short period of time were asked about their changes. The athletes affirmed that they had never taken any forbidden preparations. They affirmed that they achieved such dramatic changes naturally. The college athletes noticed that they had consumed much food for this need. So, they claimed that such evident results were reached by them because of appropriate diets. According to them, it was not difficult to gain many pounds in short period of time.
