Androstenedione: The test sensitivity for anabolic steroids in the standard LGC supplement screen is 10 ng/g (10 ppb). Androstenedione is known to be naturally present in milk and milk-derived products. The concentrations of androstenedione found in milk are variable, but are typically in the low ng/ml (low ppb) region. One reference cites values of around ng/ml. For this reason, the presence of androstenedione in milk or milk-derived supplement products and/or supplement ingredients analyzed using the standard LGC supplement screen is not reported unless the concentration exceeds 50 ng/g (50 ppb). 4
