## FAQ

#### Do testosterone boosters actually work?

Natural boosters provide modest support (10-20% improvement) for men with deficiencies or high stress. They won't match medical TRT but can meaningfully help when combined with lifestyle optimization.

#### How long until I see results?

Most men notice improved energy and mood within 2-4 weeks. Measurable testosterone changes typically require 8-12 weeks of consistent use.

#### Are these supplements safe long-term?

Ashwagandha, Vitamin D, zinc, and magnesium all have excellent long-term safety profiles at recommended doses. Always consult your doctor if you have health conditions.
