The Sigma Formula
7 Targeted Ingredients.
Zero Compromises.
Nothing replaces good sleep, diet, exercise, and stress management, but Sigma can help bridge the final gap to get you where you want to be hormonally.
Most testosterone boosters rely on underdosed ingredients, unstandardized extracts, or proprietary blends that make meaningful results unlikely. Sigma uses transparent, standardized ingredients selected for their effectiveness, backed by third-party testing and reviews that show measurable increases in testosterone.*

Elevate The Way You Feel
Low Testosterone Symptoms
THE PROBLEM
Chronically low energy, flat libido, poor recovery, and a body that stops responding aren't just signs of aging. They're signs your testosterone is fighting an uphill battle.
THE SIGMA SOLUTION
Tongkat Ali standardized to 1% Eurycomanone (HPLC-verified) and Fadogia Agrestis work at the level of androgen biosynthesis to support your body's natural testosterone production, not just mask symptoms.*
Binding Protein Drag
THE PROBLEM
Even if your testosterone isn't low, too much of it can be locked away by Sex Hormone-Binding Globulin (SHBG), leaving free testosterone levels insufficient to actually drive results.
THE SIGMA SOLUTION
Boron helps modulate binding proteins to support higher free testosterone availability, the form your body actually uses.*
Nutrient & Mineral Gaps
THE PROBLEM
Zinc, Magnesium, and Vitamin D deficiencies are among the most common in men, and all three are directly tied to testosterone production. You can't optimize what you're not even supplying.
THE SIGMA SOLUTION
Sigma includes bioavailable forms of Zinc (as Bisglycinate), Magnesium (as Bisglycinate Chelate), and Vitamin D3 to fill the gaps most diets quietly leave behind.*
Chronic Stress
THE PROBLEM
Cortisol is testosterone's natural antagonist. Elevated chronic stress, whether physical or psychological, creates a biochemical environment that actively suppresses testosterone output.
THE SIGMA SOLUTION
Patented KSM-66® Ashwagandha (standardized to 5% Withanolides) is one of the most reliable adaptogens for reducing cortisol and supporting a hormonal environment more conducive to healthy testosterone levels.*

HOW TO USE
Your Sigma Protocol
01
Take Your Capsules
Take 2 to 4 capsules, spread throughout the day. Starting with 2 is a solid baseline, increasing to 4 as needed. Do not exceed 4 capsules in any 24-hour period.
02
Stay Consistent
Sigma is a daily formula. Most of these ingredients take weeks of consistent use to reach their full effects and work best alongside consistent sleep, training, and diet.
03
Cycle It
Take Sigma daily for 1 month, then take at least 1 week off before resuming.
What Men Are Saying
Results speak for themselves.
Went from 675 to 850 total test in 2 months.
Brodie ✓ Verified
Blood Work Approved
My baseline blood work had me at 656 total T, 22 free. After 4 weeks of one capsule 4 times per day blood work showed 900 total, 177 free which was shocking.
Bob ✓ Verified
Tests prove it’s legit
I had below average testosterone on my blood test for years. I was around 450-500 and now am consistently 800-850.

Frequently Asked
What is Sigma?
Sigma is a hormone-support formula designed to help men maximize their natural testosterone output through multiple pathways: androgen biosynthesis support, binding protein modulation, filling key nutrient and mineral gaps, and cortisol reduction.*
What does Sigma actually do?
Sigma is formulated to support several of the biological factors tied to suboptimal testosterone: nutrient and mineral gaps (Zinc, Magnesium, Vitamin D3), binding protein interactions (Boron), stress-driven cortisol (KSM-66® Ashwagandha), and androgen biosynthesis in the testes (Tongkat Ali, Fadogia Agrestis). It's not a substitute for sleep, training, diet, and stress management, those remain the foundation. Sigma is designed to support what's left once those are already in place.*
What's in the formula?
Sigma contains: Vitamin D3 (as Cholecalciferol), Magnesium (as Magnesium Bisglycinate), Zinc (as Zinc Bisglycinate Chelate), Fadogia Agrestis Extract (10:1) (root), Tongkat Ali Extract (standardized to 1% Eurycomanone), KSM-66® Ashwagandha Extract (standardized to 5% Withanolides), and Boron (as Boron Citrate). Every ingredient is third-party tested and verified for identity, potency and purity.
Is this a steroid or pro-hormone?
No. Sigma contains no steroids, prohormones, or exogenous hormones of any kind. It works entirely within your body's natural endocrine system to support optimal testosterone production.
How long until I feel the results?
Most users notice improvements in energy, mood, and libido within 2 to 4 weeks of consistent daily use. Hormonal shifts take longer to develop, with fuller results typically emerging by 6 to 8 weeks.
How should I take it?
Take 2–4 capsules spread throughout the day. Do not exceed 4 capsules in a 24-hour period. Cycle: use daily for 1 month, then take at least 1 week off before resuming.
