成人男性におけるテストステロンレベルに対するQualia Testosterone+の有効性
The Efficacy of Qualia Testosterone+ on Testosterone Levels: A Triple-Armed Placebo-Controlled Parallel 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.

詳細な説明
Participants will be screened using the Aging Male Symptoms (AMS) Scale and the Androgen Deficiency in the Aging Male (ADAM) questionnaire to select candidates likely to have sub-optimal testosterone levels. Those meeting inclusion criteria will have total testosterone tested, and participants with baseline total testosterone of 500 ng/dL or less will be stratified and assigned using systematic allocation to one of three groups in a 1:1:1 ratio: Qualia Testosterone+ Formula 1, Qualia Testosterone+ Formula 2, or matched placebo.
Each participant will take 3 capsules of the assigned product once daily in the morning for 28 consecutive days. The placebo consists of vegetable/cellulose capsules containing inert rice powder, matched to the active capsules in appearance.
Blood samples for total and free testosterone (equilibrium dialysis) will be collected at baseline and day 26-28 at Ulta-affiliated phlebotomy sites, with morning collection recommended. Symptom questionnaires (AMS Scale, PROMIS Fatigue 10a, Safety and Tolerability survey) will be completed electronically at baseline, day 14, and day 28. A follow-up questionnaire will be completed at day 32-34. Regular check-in surveys will assess adherence and safety on days 1, 3, 7, 14, 21, and 28.
Statistical analyses will include paired t-tests or linear mixed-effects models for within-group differences, and linear mixed-effects models with fixed effects for group, time, and their interaction for between-group comparisons. The sample size was estimated to yield 80% power to detect an effect size of Cohen's d = 0.80 with a two-tailed t-test at a 0.05 significance level.
Note on allocation (added September 2026): Participants were assigned to study arms by systematic allocation rather than by random allocation. Earlier versions of this record described the design as randomized. The Allocation field and the design descriptions were corrected to Non-Randomized to reflect the method actually used. No other aspect of the study design, conduct, or analysis changed.
