A sports science research team in Tampa is recruiting physically active men aged 20 to 55 for a paid supplement study. Over about nine weeks, participants take a supplement that may support strength, power and endurance, and visit the Tampa facility twice for testing. Each visit includes tests of strength, power, endurance and cognition before and after the supplement period. Participants who complete the full study earn $400.
This is a good fit if you train regularly and are curious how a supplement could affect your performance. Because the study lasts around nine weeks, you need to be able to commit to both on-site visits and follow the supplement plan in between. Applications close on November 13, 2026, so apply soon if you are interested. The link opens the User Interviews screener, where you can set up a free account in a minute.
