Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study looks at whether spreading protein evenly across meals or taking a leucine supplement at breakfast can help tactical athletes (like soldiers) keep muscle and perform better during 8 weeks of hard training. Sixty-nine healthy men aged 18-35 will be assigned to one of three diet plans, all with the same total daily protein. Researchers will measure changes in lean body mass, strength, and markers of muscle damage.
