Editorial Standards
Last updated: 28 September 2026
Our Mission
The Compound is the research and commentary arm of Proven Longevity. Every article is written to help patients and practitioners navigate complex evidence without needing a PhD. We translate, contextualise, and where the evidence is thin, we say so explicitly.
Evidence Standards
Every clinical claim in a The Compound article is sourced to a primary publication (PubMed, ClinicalTrials.gov, or official regulatory body documents). We do not cite secondary press coverage as evidence for efficacy claims. We use a three-tier evidence framework:
- Tier 1 — RCT Evidence: Claim supported by published randomised controlled trials in humans.
- Tier 2 — Mechanistic Evidence: Strong mechanistic or observational data; human RCT evidence emerging or preliminary.
- Tier 3 — Emerging Evidence: Promising early data; insufficient human trials to draw firm conclusions. Labelled accordingly.
Review Process
Articles remain unpublished drafts until their sources and relevant jurisdiction have been checked and a named reviewer has signed off. Clinical and treatment articles require a qualified clinical reviewer whose credentials we check. Consumer buying guides receive a named editorial review; any medical claims in them require separate clinical review. Published articles show the reviewer and review date. We correct or withdraw articles when a material claim cannot be supported.
UK-First Regulatory Framing
The Compound is a UK publication. Regulatory references are to the MHRA and FSA exclusively. We do not apply FDA/DSHEA framing to UK regulatory questions. Where UK and US regulatory status differ materially, we state both and make the difference explicit.
Affiliate Policy
We may earn a commission from clearly labelled links to approved retailers. We identify the vendor beside a paid link and disclose the relationship before a reader follows it. A commercial offer does not determine our evidence assessment, safety warnings or ranking. We do not accept payment to alter evidence ratings. No affiliate relationship should be inferred from a product mentioned without a labelled paid link.
Sponsored Content
If we accept sponsored content, it will identify the sponsor and the nature of the relationship clearly at the start. Payment will not change evidence conclusions, safety disclosures or jurisdictional framing.
