SOURCE-LINKED STUDY SUMMARY
Short-term oxandrolone administration stimulates net muscle protein synthesis in young men.
What was studied?
A short before-and-after experiment measured muscle protein synthesis and breakdown during oxandrolone exposure.
What changed?
Muscle fractional protein synthesis increased 44%, with no change in breakdown. Net balance improved but was not statistically different from zero. Androgen-receptor mRNA increased; IGF-I mRNA did not.
Who was studied?
Six healthy young men were studied while fasting before and after treatment.
Studied exposure
Oral oxandrolone 15 mg daily for 5 days; measurements were compared with each participant’s pretreatment values.
What remains uncertain?
A five-day experiment in six men cannot quantify long-term hypertrophy or establish safety. No separate placebo group is described in the abstract.
