Editorial Standards
Last updated: June 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 We do not cite secondary press coverage as evidence for efficacy claims.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
Each article is reviewed by a named clinician with relevant credentials (GMC registration, BSLM fellowship, or equivalent) prior to publication. The reviewer's name, credentials, and review date are visible above the article fold. The reviewer confirms that claims are consistent with the cited evidence and UK regulatory status as of the review date.
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
Some articles contain affiliate links to vetted vendors. These are clearly labelled "Disclosure: paid affiliate link" inline and the relevant vendor is named. Affiliate relationships do not influence editorial decisions — the article's evidence assessment, tier classification, and safety warnings are produced independently of any commercial arrangement. We do not accept payment to alter evidence ratings.
Sponsored Content
Sponsored articles are clearly labelled with an amber "This article is sponsored" banner at the top. Sponsorship does not affect the evidence framework, safety disclosures, or UK regulatory framing. The sponsor is named and the nature of the relationship disclosed.
