This page explains how PeptideWikis entries are researched, graded, written and kept up to date.
Sources we use
Entries are built from primary sources: peer-reviewed studies (PubMed / PubMed Central), trial registries (ClinicalTrials.gov), regulators (U.S. FDA, EMA, UK MHRA, Australia’s TGA) and anti-doping authorities (WADA, USADA). Secondary sources such as news reports are used only to point to a primary source, never as evidence on their own. We do not cite vendors, forums or social media as evidence.
How we grade evidence
Every factual claim about an effect carries one of five evidence levels:
| Level | What it means |
|---|---|
| Approved use | A regulator has approved the substance for this use after reviewing trial data. |
| Human, controlled | Randomised controlled trials in people. |
| Human, early | Small, uncontrolled, observational or case-report data in people. |
| Animal | Studies in animals only. |
| Laboratory | Cell or tissue studies only. |
An effect seen only in animals or in the laboratory is described as exactly that. We do not turn animal findings into claims about people.
Doses
Where an entry lists doses, they are the doses used in published studies, with the species, route and source. They are not recommendations, and for most research peptides no human dose has been established. We do not publish dosing protocols, dose calculators or preparation and injection instructions.
Regulatory status
Each entry carries a status box (FDA approval, compounding status, WADA status and, where known, other jurisdictions) with the date it was last checked. Regulation of peptides changed several times in 2025–2026; when it changes again, entries are updated and the change is logged.
How entries are produced
Drafts are prepared with the help of AI tools, working from the primary sources listed in each entry. Every draft then passes automated checks before publication: citations must resolve to the stated source, numbers are checked against those sources, and claims without a source are removed or rewritten. The PeptideWikis Editorial Team is responsible for everything published.
Updates and corrections
Every entry shows when it was published and last updated, and significant changes are listed in the entry’s change log. If you find an error, please report it through the contact form; confirmed errors are corrected and noted.
