The testosterone optimization market is enormous and mostly noise. Before you spend money on supplements, injections, or protocols, you need to understand what the science actually says.
What Actually Suppresses Testosterone
Chronic sleep deprivation. A single week of sleeping less than 5 hours per night reduces testosterone by 15%.
Chronic stress. Cortisol and testosterone are inversely related.
Excessive body fat, particularly visceral fat, increases aromatase activity — the conversion of testosterone to estrogen.
Sedentary lifestyle. Physical training, particularly resistance training, is one of the most consistently proven testosterone boosters available.
What Actually Helps
Optimize the fundamentals: 7-9 hours of quality sleep, regular resistance training, healthy body composition, stress management, and adequate zinc and vitamin D.
