As discussed earlier in the chapter, this type of data acquisition offers possibilities to re-examine the data in post-acquisition mode and detect for analytes not initially monitored. This potential, if properly exploited, can indeed result in more efficient control of the illegal use of forbidden substances. In animal fattening is prohibited in the EU; for antibiotics, maximum residue limits are established because of their possible harmful health effects on humans.

Steroids get the best results if your dosage is specifically recommended for your body by an expert. Some users may become aggressive or combative, believe things that aren’t true , or have extreme feelings of mistrust or fear . And people who use steroids also appear to be at higher risk for using other drugs, such as alcohol or cocaine, often to counteract some of the negative effects of steroids.

However, the percentage of participants who practiced between 6 months and 1 year was already increasing in the Gfu group, equivalent to that in the Gnu group. The percentage of participants who practiced between one and 3 years was the highest in the Gfu group. The percentage of those who practiced for more than 3 years was higher in the Gex, Gus, and Gfu groups. Among these participants, 83.2% did not use, 9.1% formerly used, 3.4% currently used, and 4.3% intended to use AS. The prevalence of AS use in the Gex and Gus groups was 16.9 and 6.5% among men and women, respectively. A pre-training with researchers was conducted to standardize the approach and application of the questionnaire.
Changes in the male reproductive system are often reversible, if anabolic steroids have not been abused for a long period of time. Estimates of lifetime incidence of anabolic steroid abuse range from 0.5 to 5% of the population, but subpopulations vary significantly . In the US, the reported rate of use is 6 to 11% among high school–aged males, including an unexpected number of nonathletes, and about 2.5% among high school–aged females.

The first step in treating anabolic steroid abuse is to discontinue use and to seek medical help in order to address any psychiatric or physical symptoms that might occur.
