IF you surf the Internet or browse men’s magazines in search of strategies for boosting muscle or trimming fat, you may have come upon a strange phrase: hormone secretagogues. Advertisements and Web sites claim that these pills, powdered drinks, and nasal or oral sprays will not only buff your body but also strengthen bones, sharpen wits and banish wrinkles and gray hair.
Scientists say there is no solid research to support the hype about these all-natural products, which are available without a prescription in stores that sell dietary supplements and over the Internet. However, many of those same scientists insist that the concept of a hormone secretagogue – that is, a compound that can trigger the release of vital chemical messengers in the body – holds great promise.
