Review Guidelines & Methodology

How we research, evaluate, and recommend substances and products — and the standards we hold ourselves to.

Substance Evaluation Criteria

When evaluating a nootropic substance, we assess the following dimensions:

Clinical Evidence

Quality and quantity of peer-reviewed human trials. We prioritize RCTs and meta-analyses over animal or in-vitro studies.

Mechanism of Action

How well the compound's mechanism is understood. Well-characterized pathways increase our confidence in efficacy claims.

Safety Profile

Known side effects, drug interactions, and long-term safety data. We flag substances with limited safety research.

User Experience

Real-world reports from our own testing and community feedback. Subjective effects are noted separately from clinical data.

Dosing Clarity

Whether effective doses are well-established in the literature and practically achievable with available products.

Regulatory Status

Whether the substance is DSHEA-compliant, requires research-use-only framing, or has regulatory concerns.

Product Review Criteria

When reviewing specific products, we evaluate:

  1. Ingredient quality — branded/patented ingredients, bioavailable forms, effective dosages
  2. Label transparency — no proprietary blends, clear dosing, accurate ingredient list
  3. Third-party testing — independent COAs, heavy metal testing, purity verification
  4. Manufacturing standards — GMP certification, NSF or USP verification when applicable
  5. Value — cost per effective serving relative to alternatives
  6. Company reputation — track record, customer service, return policy

Rating Scale

Products are rated on a 1–5 scale:

  • 5 — Excellent: Best-in-class. Exceptional quality, transparent label, strong evidence base, and great value.
  • 4 — Very Good: High quality with minor drawbacks. Recommended for most people.
  • 3 — Average: Decent option but notable limitations. Better alternatives may exist.
  • 2 — Below Average: Significant concerns with quality, dosing, or value.
  • 1 — Not Recommended: Serious quality, safety, or transparency issues.

Editorial Independence

Our reviews are editorially independent. We may earn affiliate commissions on recommended products (see our Affiliate Disclosure), but commission rates never influence scores or recommendations. We have given poor ratings to products with active affiliate relationships.

Corrections & Updates

Science evolves, and so does our content. We regularly update substance monographs and product reviews as new research emerges. All articles include a "last updated" date. If you spot an error, please contact us.
