PURPOSE: Methoxyisoflavone (M), 20-hydroxyecdysone (E), and sulfo-polysaccharide (CSP3) have been
marketed to athletes as dietary supplements that can increase strength and muscle mass during resistancetraining.
However, little is known about their potential ergogenic value. The purpose of this study was to
determine whether these supplements affect training adaptations and/or markers of muscle
anabolism/catabolism in resistance-trained athletes. METHODS: Forty-five resistance-trained males (20.5±3
yrs; 179±7 cm, 84±16 kg, 17.3±9% body fat) were matched according to FFM and randomly assigned to ingest
in a double blind manner supplements containing either a placebo (P); 800 mg/day of M; 200 mg of E; or, 1,000
mg/day of CSP3 for 8-weeks during training. At 0, 4, and 8-weeks, subjects donated fasting blood samples and
completed comprehensive muscular strength, muscular endurance, anaerobic capacity, and body composition
analysis. Data were analyzed by repeated measures ANOVA. RESULTS: No significant differences (p>0.05)
were observed in training adaptations among groups in the variables FFM, percent body fat, bench press 1RM,
leg press 1RM or sprint peak power. Anabolic/catabolic analysis revealed no significant differences among
groups in active testosterone (AT), free testosterone (FT), cortisol, the AT to cortisol ratio, urea nitrogen,
creatinine, the blood urea nitrogen to creatinine ratio. In addition, no significant differences were seen from pre
to post supplementation and/or training in AT, FT, or cortisol. CONCLUSION: Results indicate that M, E,
and CSP3 supplementation do not affect body composition or training adaptations nor do they influence the
anabolic/catabolic hormone status or general markers of catabolism in resistance-trained males. Journal of the
