Healthy Physically Fit Adults Regularly Exercising Adults Mib 626

ClinConnect Summary

This clinical trial is investigating the effects of a supplement called MIB-626, taken alongside a high-intensity exercise program, on healthy individuals aged 19 to 40 who are already physically fit. Participants will be randomly assigned to either receive the supplement or a placebo (a sugar pill) twice a day for 10 weeks. The goal is to see how MIB-626 affects their physical performance and overall health when combined with a structured exercise routine aimed at improving strength, endurance, and energy levels.

To be eligible for this study, participants must be very active, exercising vigorously at least four days a week for 30 minutes or more, and have a body mass index (BMI) between 18.5 and 32. They should be free from significant health issues and willing to commit to the 10-week exercise program. Women must not be pregnant or planning to become pregnant during the trial. Participants can expect to engage in intense workouts designed to enhance their fitness, and they will receive regular health monitoring throughout the study. Additionally, they should be prepared to avoid certain medications and supplements during the trial to ensure accurate results.
