Research summaries
Plain-English summaries of what published research says about each peptide, with citations to PubMed and review papers.
About Peptide Intelligence
A research-peptide intelligence and vendor-comparison site. We make publicly available information easier to find, compare, and evaluate — we do not sell peptides and we do not provide medical advice.
What the site does
Vendor comparisons
Side-by-side normalized price-per-mg listings across the vendors we track, with stock status and verification flags.
Transparency signals
Per-vendor signals — COA availability, third-party tests, policy clarity — surfaced individually rather than baked into a single score.
What the site does not do
Drawing the boundary explicitly so it is clear what kind of resource this is.
- Sell or fulfil peptidesNo
- Provide medical adviceNo
- Publish dosage or treatment protocolsNo
- Make safety or efficacy claims about specific compoundsNo
- Make legal or regulatory determinations for your jurisdictionNo
How the site is built
- Automated collection
- Narrow scrapers read publicly visible product pages on a per-vendor cadence published on the scraper policy page.
- Human-reviewed editorial
- Any copy touching medical, regulatory, or safety language is reviewed by a human before publication.
- Published methodology
- Ranking inputs and the transparency-signal list are public and versioned in a changelog.
- Privacy-light analytics
- Page views and outbound clicks are tracked anonymously. No personal identifiers; details on the privacy policy page.
- Vendor opt-out
- Vendors can exclude themselves with a two-line robots.txt rule; no email required.
Full ranking process and refresh cadences live on the methodology page.
Editorial standards
- Research summaries cite primary sources; we do not paraphrase vendor marketing as fact.
- We separate observation from recommendation — vendor data is presented; the user decides.
- We do not write in the second person about what you should buy, take, or dose.
- We correct factual errors quickly and note the date of any material change.
- We disclose affiliate relationships on every page where an affiliate link appears.
A note on regulation
Most peptides discussed on this site are not FDA-approved for the uses described in research literature. Many are sold under "research use only" labeling. Laws vary by jurisdiction. Nothing on this site should be interpreted as a recommendation to purchase, possess, or use any peptide.
