The promise
Every check traces a claim to its primary source, quotes it exactly, grades the evidence GRADE-style (A high to D very low), follows the funding, and names the limits out loud.
Press & media kit
Built to be cited.
Caveat is the independent, evidence-based claim-checker for the longevity industry. Everything here is free to quote. If you are writing about a supplement, peptide, device or protocol, the verdicts below are sourced, graded and ready to reference.
What we are
Independent. Sourced. Anti-hype.
Caveat checks what influencers and brands claim about supplements, peptides, wearables and biomarker tests against what the evidence actually shows, sources cited, evidence graded GRADE-style, conflicts of interest flagged, and the limits named out loud. Independent. No industry money.
The independence
No industry money, no affiliate revenue behind a verdict. When the evidence is thin we say “unproven,” not “disproven.” When a claim holds up, we say so.
