A single published Peptide Institute test represents an anonymous product purchase, chain-of-custody shipping, and analytical laboratory fees — before any editorial time. Multiply by confirmation retests for failures and the cost of a testing program explains why affiliate review sites, which monetize recommendations rather than verification, almost never test products.
We publish this breakdown because our independence claims should themselves be inspectable. The Peptide Institute accepts no sponsorships or paid placements; the methodology page documents our funding model.
