SOURCE-LINKED STUDY SUMMARY
Bodybuilders' body composition: effect of nandrolone decanoate.
Abstract summarizedQuality not appraised
- What was studied
- A randomized, double-blind, placebo-controlled trial tested nandrolone’s effects on body composition in trained bodybuilders.
- Who / model studied
- 16 experienced male bodybuilders aged 19 to 44 years.
- Studied dose & schedule
- Nandrolone decanoate 200 mg intramuscularly weekly, or placebo, for 8 weeks.
- What the study found
- Nandrolone increased body mass by 2.2 kg, fat-free mass by 2.6 kg and total body water by 1.4 kg. Fat mass and fat-free-mass hydration did not significantly change.
- Limitations & context
- This small, short trial measured body composition; fat-free mass and water gains are not separate measurements of newly formed contractile muscle.
