What We Cover
We focus on supplements used for strength, hypertrophy, endurance, recovery, focus, and related health support when those outcomes matter to training decisions.
About
Evidence-first supplement ratings for skeptical lifters.
Evidence Stack exists to help people separate useful gym supplements from weak claims, redundant products, and overconfident marketing. Each rating is tied to a specific claim, source list, dose context, and caveat.
What We Do Not Do
We do not provide medical advice, diagnose conditions, or treat biomarker changes as automatic proof of better training outcomes.
How Trust Is Built
Strong claims need strong sources. Where the evidence is limited, mixed, indirect, or product-specific, the rating and caveat make that clear.
Current Coverage
The catalog currently covers 129 popular supplements with 731 linked evidence sources. Ingredient-level ratings come first; specific product picks require separate checks for dose, form, label transparency, third-party testing, contaminants, sport-risk disclosures, and value.
