Editorial Policy

This page explains how content is created, reviewed, updated, and corrected on Peptide CostCalc. Transparency about our process is central to the site.

How Content Is Written

• Formula-first: Every calculator is built from a published or verifiable formula, documented before the calculator is coded.
• Plain language: Explanations are written for researchers who may not have a clinical background. Jargon is explained on first use.
• No health claims: Content never makes therapeutic claims, recommends specific dosing for humans, or implies a compound is safe or effective for any condition.
• Context and limitations: Every calculator page notes what the tool does, what it does not do, and where estimates may diverge from reality.

Formula Verification Process

Before a calculator is published, its formula is verified by:

1. Identifying the primary source (peer-reviewed paper, pharmacokinetic textbook, or established compounding reference)
2. Manually working through at least three example calculations to confirm the formula matches expected outputs
3. Cross-checking against at least one independent reference where available
4. Testing the calculator with boundary inputs (zero values, very large values, unit switches) to confirm edge cases are handled correctly

All verified formulas and sources are listed on the Sources and Methodology page.

Use of AI Tools

AI tools (including large language models) are used to assist with code generation, content drafting, and research summarisation. All AI-generated content is reviewed and edited by a human before publication and is never published without verification against primary or authoritative sources. AI is not used to generate medical claims, dosing recommendations, or clinical guidance.

Human Review Process

Every calculator and every piece of editorial content is reviewed by a human before publication. This review checks: mathematical accuracy, unit conversion correctness, readability, appropriate disclaimers, and internal links to related tools and the methodology page.

How Often Content Is Updated

Calculators are reviewed and updated when a user reports a potential error, a new authoritative source supersedes the current reference, a formula assumption is found to be outdated, or a UI or accessibility improvement is identified.

How to Report a Mistake

If you find a factual error, formula mistake, or misleading statement, please contact us via the Contact page with the URL, a description of the error, and your suggested correction with a supporting source. We aim to review all reports within 5 business days.

Corrections Policy

When a formula or factual error is corrected, a correction notice is added to the affected page. Significant corrections are also noted on the Sources and Methodology page. We do not silently edit content to remove errors.
