Methodology

Independence

Pepsignal accepts no compensation from peptide vendors, compounding pharmacies, clinics, or service providers in exchange for editorial coverage. We do not run paid promotions, affiliate offers, or sponsored sections. Subscription revenue is the only revenue.

Three-tier signal labeling

Every claim in a Pepsignal brief is labeled with one of three tiers:

• Public fact— verified against a primary source (regulator notice, court filing, public company disclosure, archived vendor page). The source is linked.
• Editorial assessment— Pepsignal’s interpretation of public facts. Clearly marked as opinion.
• Unverified signal— circulating in the industry but not yet confirmed. Reported with the caveat “unverified” in plain language.

Source provenance

Every factual claim links to a primary source. When a primary source is behind a paywall, we link to it anyway and note the paywall. We do not cite anonymous sources without a parallel public-record corroboration.

What we don’t cover

Pepsignal does not publish therapeutic claims, dosing recommendations, vendor rankings, or buying guides. We do not identify individual patients, prescribers, or pharmacists by name except where they have already chosen to operate publicly (e.g., named in a regulatory action, quoted in a public filing, or operating an identified business).

Corrections

Material errors are corrected promptly and disclosed in the next issue and on the corrections page. We do not silently update published material.

Right of reply

Any company, clinic, or person named in a Pepsignal brief may submit a written response. Responses received before the following Tuesday’s publication will be considered for inclusion in that issue’s right-of-reply section.
