Testosterone boosters vs TRT
Over-the-counter dietary supplements and prescription testosterone therapy are not interchangeable categories.
Supplements
Dietary supplements may carry qualifying structure/function claims when regulatory requirements are met, but they cannot legally be marketed as products that diagnose, treat, cure or prevent disease.
Prescription therapy
Prescription testosterone is medical treatment requiring clinical evaluation and professional oversight. If you have symptoms or concerns about hormone levels, seek qualified medical care rather than self-diagnosing from supplement advertising.
