Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The general hypothesis is that administration of testosterone to healthy, older men for 52 weeks (1 year) following a cycle of 4 weeks of testosterone administration and 4 weeks without testosterone (i.e., monthly cycled regimen) will provide the same gains in muscle strength, muscle mass, and bone density as standard of care (SOC), continuous administration of testosterone for 52 weeks.
