Other steroids, sometimes called steroidal supplements, contain 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. But research studies suggest that they do very little or nothing to improve athletic performance.
