Testosterone Boosters

Over-the-counter testosterone boosters, such as those featuring tribulus terrestris or fenugreek, fail to produce clinically meaningful testosterone increases, with a 2022 meta-analysis of 12 controlled trials showing no significant change in total testosterone levels. D-aspartic acid, another common ingredient, has been linked to an average 12% increase in some studies, but this is less than the 15-30% boost typically seen with supervised resistance training alone. These products often cost $30-$60 per month, yet they underperform simpler lifestyle interventions like sleep optimization or weight loss in improving testosterone. Compared to #4 on our list, which at least shows minor acute effects, these boosters consistently deliver no statistical benefit over placebo in rigorous trials.
