This page explains how we research, write, check and update every page on PeptideInfo.io.
Our sources
We build each page from primary sources. These include peer-reviewed studies indexed in PubMed, trial records on ClinicalTrials.gov, FDA labels and announcements, and the World Anti-Doping Agency Prohibited List. We link to every source we cite.
We do not use seller websites, forum posts or social media as evidence.
How we rate evidence
Each library page shows the strongest evidence published so far, on a five-step scale:
- Lab and cell studies. Results in dishes and test tubes.
- Animal studies. Results in mice, rats or other animals.
- Early human studies. Small or uncontrolled studies in people.
- Controlled human trials. Randomized trials with a comparison group.
- FDA-approved use. The FDA approved the peptide for a specific use after review.
A higher step does not mean a peptide is safe for every use. It means stronger evidence exists for at least one use. We explain which use on each page.
Fact-checking
Before we publish a page, we check every fact against its original source. That means the study itself, the trial record or the FDA label, not a news story about it. We check the evidence rating and the safety information the same way.
PeptideInfo.io does not have licensed medical reviewers yet. Each page shows who wrote it and when we last checked it. We plan to add licensed reviewers as the site grows. Any page reviewed by a licensed professional will name that person at the top.
What we leave out
We do not publish dosing protocols, mixing or injection guides, or “stacks.” We do not say a peptide treats a condition unless an FDA-approved label says so.
Updates and corrections
We recheck each library page at least once a year, and sooner when new trials or FDA actions appear. If you spot an error, tell us through our contact page. We fix confirmed errors fast and note major corrections on the page.
Independence
Advertisers and affiliate partners have no say in what we write. Our writers do not choose which ads run on a page.
Use of AI tools
We sometimes use AI tools to help organize research notes or draft outlines. A person checks every fact against the original source before any page goes live.
