Androgenic anabolic steroid (AAS) interventions with effects that are unclear if meaningful
Androstenidone (testosterone precursor) at 300 mg a day for 7 days increased total T by 34%, and total estradiol by 24% on average, in young men (Leder et al., 2000).
A 2007 review on testosterone DHEA, androstenedione, and androstenediol concluded that “ Studies have demonstrated repeatedly that acute and long-term administration of these oral testosterone precursors does not effectively increase serum testosterone levels and fails to produce any significant changes in lean body mass, muscle strength, or performance improvement compared with placebo.” (10.1016/j.pcl.2007.05.002).
Interventions with no meaningful effects
DHEA 100mg/day for 28 days was found to have no effect on exercise performance in athletic women (doi: 10.1055/a-0631-3008).
DHEA 100mg/day for 28 days in young athletic men had no effect on body composition or BMI (https://www.ncbi.nlm.nih.gov/pubmed/21789881)
60 mg prednisone a day for 1 week in young men had no effect on exercise performance (doi: 10.1016/j.steroids.2014.04.008).
