PY - 2021 T2 - Essentials of Men’s Health AB - Clinicians of all types are likely to encounter male patients who have used various types of body-appearance and performance-enhancing supplements or drugs. Particularly important among these substances are anabolic-androgenic steroids (AAS), which are illegal without a prescription in the United States, but are easily obtained illicitly through the Internet or from underground dealers. Some men use AAS and other substances to improve athletic performance, but a substantially larger percentage have no athletic aspirations when using these substances and instead are attempting to improve their personal appearance by gaining muscle and losing body fat.1 SN - PB - McGraw Hill CY - New York, NY Y2 - 2024/04/20 UR - accessmedicine.mhmedical.com/content.aspx?aid=1174516619 ER -
