Frequently Asked Questions

Do testosterone booster supplements actually work?

Most OTC testosterone boosters have limited evidence. Ashwagandha (KSM-66) has the strongest data showing 10-15% increases. Lifestyle factors like sleep, exercise, and weight management are more impactful.

What are signs of low testosterone?

Fatigue, low libido, erectile dysfunction, decreased muscle mass, increased body fat, mood changes, and brain fog. A blood test measuring total and free testosterone is needed for diagnosis.

Can exercise increase testosterone?

Yes. Resistance training (weightlifting) consistently shows 15-20% acute increases in T levels. High-intensity interval training (HIIT) also helps. Overtraining can have the opposite effect.
