Protocol Categories
12 categories of testosterone optimization.
Every protocol is categorized, tiered by evidence level, and scored by impact. Pick what fits your life.
Sleep
Optimize your sleep environment for maximum T production during deep sleep cycles.
Light Exposure
Morning sunlight and light timing to set circadian rhythm for optimal hormone production.
Exercise
Compound lifts and HIIT sprints that trigger the greatest hormonal response.
Breathing
Nasal breathing and breathwork protocols to increase nitric oxide and reduce stress.
Stress Management
Physiological sigh and cortisol-lowering techniques. Cortisol is the #1 T killer.
Supplements
Zinc, Magnesium, D3, Ashwagandha, Tongkat Ali, and more — evidence-rated.
Cold Therapy
Cold showers, ice baths, and testicular cooling for hormetic stress response.
Heat Therapy
Finnish-style sauna sessions for growth hormone release and recovery.
Lifestyle
NoFap, grounding, EMF reduction, dopamine detox, and mewing protocols.
Diet
Carnivore and nutrition protocols that support steroid hormone synthesis.
Sexual Health
Semen retention and abstinence cycling for testosterone and androgen receptor sensitivity.
Biohacking
Red light therapy and cutting-edge protocols for mitochondrial function and Leydig cell support.

Strong Evidence
12 pts
Compound Lifting
Squat, deadlift, bench press, overhead press. Large muscle group engagement triggers the greatest hormonal response.
Strong Evidence
8 pts
Core Micronutrient Stack
Zinc (30mg), Magnesium (400mg), Vitamin D3 (5000IU), Boron (10mg). The foundational supplements most men lack.
Strong Evidence
7 pts
Stress Management
Physiological sigh: double inhale through nose, long exhale through mouth. Cortisol is the #1 testosterone killer.
Strong Evidence
6 pts
Morning Sunlight
10-30 min of bright light within the first hour of waking. Sets circadian rhythm and boosts vitamin D synthesis.
Strong Evidence
5 pts
HIIT Sprints
8-10 intervals of 30-second all-out effort. Triggers massive growth hormone and testosterone release.

The Huberman Stack
Andrew Huberman's evidence-based protocol for hormonal optimization. Morning sunlight, cold exposure, compound lifting, Tongkat Ali, Fadogia, and stress management.
6 protocolsThe Fundamentals
Start here. Sleep optimization, morning sunlight, compound lifting, core micronutrients, and stress management. The essential protocols every man should follow.
5 protocolsThe Sigma Grindset
Maximum discipline. Cold exposure, compound lifting, HIIT sprints, semen retention, NoFap, and dopamine detox. For those who want the hardest path.
6 protocolsThe Ancestral Stack
Return to primal. Sunlight, grounding, carnivore diet, nasal breathing, cold exposure, and EMF reduction. Protocols based on ancestral living principles.
6 protocolsThe Supplement Maximizer
Full supplement protocol: core micronutrients, Ashwagandha KSM-66, Tongkat Ali LJ100, and Fadogia Agrestis. Minimal effort, maximum supplementation.
4 protocolsThe Natty Score
One number. Your optimization level.
The Natty Score is a weighted metric (0-100) based on your daily protocol completion. Higher-impact protocols like sleep optimization (15 pts) and compound lifting (12 pts) contribute more than lower-impact ones. It's designed to help you prioritize what actually moves the needle.
