Anabolic ("muscle-building") steroids are man-made substances closely linked to the male hormone testosterone. These drugs are available by prescription only to treat certain medical conditions. They are only safe for use when taken under a doctor's care and supervision. Abuse of steroids — often in an attempt to gain more muscle mass — can lead to serious health problems, some of which are irreversible.Another group of steroids, sometimes called steroidal supplements, contains dehydroepiandrosterone (DHEA) and/or androstenedione (also known as andro). For the most part, steroidal supplements, which used to be found at health food stores or gyms, are now illegal and require a prescription. DHEA is one of the few exceptions and can still be bought over the counter.
Steroid supplements are weaker forms of androgen. Their effects aren't well known, but it's thought that, when taken in large doses, they cause effects similar to other androgens like testosterone. Here's what is known about steroidal supplements: Companies that manufacture them often use false claims and very little is known about the long-term effects some of these substances have on the body. That’s one reason why the government took action to protect citizens by passing laws controlling steroid distribution.
