Sold as Dietary Supplements: NOT
from the desk of Ted Duboise
A public health advisory warning has been issued to consumers by the U.S. Food and Drug Administration (FDA) on July 28, 2009. The FDA is warning people to stop using any body-building products in which the label states that the product contains steroids or steroid-like substances. Many of these products are marketed as dietary supplements, however, they are NOT dietary supplements, but instead are unapproved and misbranded drugs.

I would take anything the FDA says with a grain of salt.
Ingredient lists should always be scrutinized by the consumer, however, some plant saponins are classified as sterols:beta-sitosterol, alpha-spinasterol for example are components in alfalfa.
Plant sterols only become dangerous drugs when they are extracted and isolated, removing the mitigating effects of their cofactors.
