The Effect of Nandrolone Decanoate and Leucine on Muscle Loss (Le-Na)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02376309
Recruitment Status : Completed

Brief Summary:
A decrease in muscle mass can have a profound impact on quality of life, as it can lead to decreased strength, insulin resistance, lower basal metabolic rate and obesity. With this study we investigate whether ingesting leucine or getting a ND injection will reduce the loss of muscle mass and strength.
