About this trial
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.

Treatment groups
Trial outcomes
Primary outcomes
Change in Total Testosterone Levels
Between-group change in serum total testosterone concentration from baseline to Day 28, measured via venous blood draw analyzed by a CLIA-certified laboratory. Comparison across Qualia Testosterone+ Formula 1, Formula 2, and Placebo groups using linear mixed-effects models.
Secondary outcomes
Change in Free (Dialysis) Testosterone Levels
Between-group change in serum free testosterone concentration measured by equilibrium dialysis from baseline to Day 28, via venous blood draw analyzed by a CLIA-certified laboratory.
Change in Aging Males' Symptoms (AMS) Scale Score
Between-group change in the Aging Males' Symptoms (AMS) Scale total score from baseline to Day 28. The AMS Scale is a validated 17-item self-reported questionnaire assessing symptoms associated with aging and declining testosterone in males.
Change in PROMIS Fatigue 10a Score
Between-group change in the PROMIS Fatigue 10a short form T-score from baseline to Day 28. The PROMIS Fatigue 10a is a validated 10-item self-reported questionnaire measuring fatigue severity and its impact on daily functioning over the past 7 days.
Safety and Tolerability
Within- and between-group changes from baseline to Days 14 and 28 in side effect profile using a custom Safety and Tolerability survey assessing symptoms including nausea, headache, mood changes, dizziness, bloating, itching, and sexual dysfunction.
