About the study
This is a double-blind, placebo-controlled, triple-arm, parallel-group study evaluating the efficacy and tolerability of two distinct Qualia Testosterone+ formulations, novel dietary supplements formulated to support endogenous testosterone, in adult males aged 28-65. Approximately 75 participants will be assigned equally to receive Qualia Testosterone+ Formula 1, Qualia Testosterone+ Formula 2, or a matched placebo (3 capsules once each morning) for 28 days. The primary outcome is between-group change in total testosterone from baseline to day 28. Secondary outcomes include changes in free (dialysis) testosterone, the Aging Male Symptoms Scale, the PROMIS Short Form v1.0 - Fatigue 10a, and safety and tolerability assessments. Blood samples will be collected in a clinical laboratory setting, while symptom and safety assessments will be completed electronically at home.
