Comprehensive Natural Testosterone Support
Gorilla Mind Sigma is a thoughtfully formulated testosterone support supplement designed to assist healthy testosterone levels by addressing multiple underlying factors — nutrient status, androgen production, binding proteins, and stress physiology.
Rather than relying on a single “hero ingredient,” Sigma takes a systems-based approach to endocrine support, making it well suited for men looking to optimise natural hormone output before considering more aggressive interventions.
This is not a shortcut or replacement for good sleep, nutrition, training, and stress management, but it can be a powerful adjunct when those fundamentals are already in place.
Healthy total and free testosterone levels
Androgen biosynthesis in the testes
Hormone-binding protein modulation
Stress and cortisol management
Male fertility and reproductive health markers
Sigma uses clinically studied, third-party tested ingredients in bioavailable forms, including:
Longjack (1% Eurycomanone, HPLC tested) – supports free testosterone and libido
KSM-66® Ashwagandha – helps manage stress and cortisol while supporting testosterone output
Key minerals and nutrients – address common micronutrient gaps linked to suboptimal hormone levels
Binding protein support – helps improve testosterone availability, not just production
By targeting both production and utilisation pathways, Sigma supports a more favourable hormonal environment without overstimulation.
Take 2–4 capsules daily, spread throughout the day
Cycle 1 month on, 1 week off
Do not exceed 4 capsules in a 24-hour period
Sigma stands out for its measured, evidence-driven approach to testosterone support. It avoids extreme dosing, questionable claims, and gimmicks, focusing instead on fundamentals that actually matter for long-term endocrine health.
