Evidence-Based Longevity Protocols

Stacking Years protocols are curated stacks of high-leverage longevity interventions, organised by goal, budget, and philosophy. Each protocol includes a daily, weekly, and quarterly schedule, supplement recommendations, and the evidence rationale for every included intervention.

• The Gold Standard — Everything that works, no compromises — the comprehensive premium stack with diagnostics, training, supplementation, and physician-supervised pharmacology.
• The Zero-Cost Baseline — Maximum longevity impact using only what nature and time provide — no spending required.
• Budget-Optimized Essentials — The highest return-on-investment interventions for under $100/month — every item RCT-backed.
• The Pragmatic Pioneer — Strong mechanistic evidence + promising early human data = worth adding to the stack.
• Cognitive Longevity — Optimized specifically for neuroprotection, synaptic plasticity, and dementia prevention.
• Physical Robustness — Optimized for bone density, muscle mass retention, and mobility — the physical foundation of independent aging.
• Metabolic Restoration — Designed for optimizing insulin sensitivity and lipid profiles through targeted dietary timing, exercise, and supplementation.
• Time-Poor / High-Efficiency — Maximum longevity ROI for busy professionals — minimum effective dose, zero waste.
• Travel-Friendly — A longevity protocol that requires zero equipment and survives time zones, hotel rooms, and airport food.
