• Conditions: Testosterone

• Registration Number: NCT02600650
• Lead Sponsor: Canadian Memorial Chiropractic College

Brief Summary

The purpose of this study is to determine whether a proprietary 'testosterone-boosting' supplement, when used as recommended by the manufacturer, results in an increase in testosterone levels as measured by a salivary free testosterone assay.

Detailed Description

The experimental intervention in this study is the daily administration of a testosterone boosting supplement or sham supplement for 4 weeks. The supplement will be administered daily in capsule form. The control group will be given a sham capsule containing the carrier components of the supplement. Participants will be asked not to modify their current lifestyle. Salivary testosterone levels will be assessed prior to the intervention to collect a baseline measurement for each subject, and following the intervention to evaluate any changes in hormone levels.
