Disclaimer
Please read before using Everspan.
Not Medical Advice
Everspan is an information and research aggregation platform. Nothing on this website constitutes medical advice, diagnosis, or treatment. The content – including evidence grades, dosage guides, mechanism of action summaries, risk assessments, and sourcing links – is provided for educational and informational purposes only.
Always consult a qualified healthcare professional before starting, stopping, or modifying any supplement, medication, or health intervention. This is especially important if you have a pre-existing medical condition, are pregnant or breastfeeding, or are taking prescription medications.
Evidence Grades Are Our Assessment, Not a Medical Standard
The evidence grading system (A through F) used on Everspan is our own editorial framework based on publicly available research. It is intended to help users understand the relative strength of evidence behind an intervention – not to make therapeutic claims. Our grades represent a snapshot of the literature at the time of last verification and may not reflect the most recent published research.
Human trial counts, participant numbers, and research velocity data are sourced from PubMed and Semantic Scholar. These figures are approximate and subject to the limitations of automated database queries.
Affiliate Disclosure
Some "Where to Source" links on Everspan are affiliate links. This means we may earn a small commission if you purchase a product through those links, at no additional cost to you. Affiliate relationships do not influence our evidence grades, risk ratings, or editorial content. We only show sourcing links for interventions rated B- evidence or higher.
Everspan does not manufacture, sell, or endorse any specific supplement brand or product. The vendors listed are provided as a convenience. Always verify product quality, dosage, and third-party testing before purchasing any supplement.
Accuracy and Currency of Information
We make reasonable efforts to ensure the accuracy of content on Everspan. However, longevity science moves quickly. Research findings can be updated, contradicted, or superseded. The "Last verified" date shown on each intervention page indicates when we last reviewed that content – not when the underlying research was published.
If you believe any information on Everspan is inaccurate or outdated, please use the "Flag inaccuracy" button on the relevant page. We review all reports and update content accordingly.
Legality Information
Legal status information is provided as a general guide only. Laws and regulations around supplements, pharmaceuticals, and medical procedures vary by country, region, and over time. The information on Everspan should not be relied upon as legal advice. Always verify the current legal status of any substance in your jurisdiction before obtaining or using it.
No Endorsement of Self-Experimentation
Some interventions listed on Everspan – particularly pharmaceuticals, peptides, and experimental therapies – carry significant risks and require medical supervision. The presence of an intervention on this platform does not constitute an endorsement of self-administration. Several listed compounds are not approved by the FDA or equivalent regulatory bodies for the purposes described.
External Links
Everspan links to external websites including PubMed, Semantic Scholar, and vendor sites. We are not responsible for the content, accuracy, or privacy practices of third-party websites. Linking to a source does not imply endorsement of its content beyond the specific paper or page cited.
Limitation of Liability
To the fullest extent permitted by law, Everspan and its operators disclaim all liability for any harm, loss, or damage arising from use of or reliance on information on this platform. Use of Everspan is at your own risk.
