Big Stack

78/100 science score
$449 price
Promoted by Bryan Johnson

Overview

Effectiveness scores 70 due to robust evidence for creatine (multiple RCTs/meta-analyses show improved strength/muscle in older adults at 3-5g/day, e.g., Examine.com summaries) and emerging data for taurine (animal lifespan extension, human trials ongoing), but longevity claims rely on preliminary senolytics (fisetin RCTs limited to intermittent dosing) and NAD+ boosters (NR RCTs like 2025 study no muscle benefits). Safety near-perfect (95) as doses match clinical trials (e.g., Ca-AKG 1-2g safe)

Key strengths

Strong evidence for muscle/energy benefits from creatine/taurine.
Comprehensive longevity protocol with transparent third-party testing.
High customer satisfaction (4.8/5 from 2000+ reviews).

Our analysis

Big Stack offers a well-tested, science-inspired longevity/muscle stack with strong components like creatine but overhyped anti-aging benefits lacking robust human trials. Good for optimized health routines if budget allows; otherwise, prioritize creatine/taurine individually. Consult doctor before starting.
