www. Androstenedione (andro) is a steroid that is thought by some athletes to increase strength. Researchers investigated this claim by collecting a random sample of men and randomly assigning half to receive andro and the other half to receive a placebo. One of the variables measured in the study was the increase in "lat pull down" strength (in pounds) of each subject after 4 weeks. (A lat pull down is a type of weightlifting exercise.)
