Federal officials have announced a long-planned crackdown on companies that make steroidlike dietary supplements with a promise that, by year’s end, a law will classify the products as illegal controlled substances, reports the Newark Star-Ledger. The supplements, referred to as andro — short for androstenedione — became well-known in 1998 after then-St. Louis Cardinals slugger Mark McGwire admitted to using them to build muscle strength.
One supplement maker said the government’s actions appeared to be a reaction to revelations about Balco, a California sports nutrition company that allegedly made and sold designer steroids.
The supplements at issue are sold over the counter in gyms and stores and are commonly marketed as performance enhancers. After anabolic steroids were outlawed in 1990, andro products emerged on the market as dietary supplements.
