Thomson, J., Quindry, J., Brittingham, K., Panton, I., Breuel, J., Farnest, C., Olson, M., & Broeder, C. (2000). The andro project: Effects of androstenediol or androstenedione on strength in men. Medicine and Science in Sports and Exercise, 32(5), Supplement abstract 795.

Males (N = 5; ages 35-65 yr), participating in a 12-week high intensity resistance training program (3 times per week), were randomly assigned to one of three groups (placebo; androstenediol (200 mg/d), or androstenedione (200 mg/d).

Neither andro supplement enhanced training adaptations over those demonstrated by the placebo group. There were no differences for weakest, least experienced, strongest, or most experienced Ss. It was proposed that all changes were likely to be neurological in origin as would be expected in older men for a short term training period.

Implication. Andro supplements do not produce strength enhancements in ordinary aged males. It should not be concluded that no effect occurs in trained athletes.
