About
About PeptideIndex
An independent, non-commercial reference for people researching peptides — what it covers, where the information comes from, and what it cannot tell you.
What PeptideIndex is
PeptideIndex is a reference database of research peptides. It currently holds 20 compound profiles, 20 educational guides, side-by-side comparison pages, reconstitution and dosing calculators, a curated video index and a supplier price comparison built from publicly listed prices.
Each compound profile records the same fields — mechanism, reported benefits, considerations, side effects, half-life, administration route, commonly reported dosing, storage, legal status and an evidence grade — so that compounds can be read against one another rather than in isolation.
Why it exists
Most peptide information online sits either behind a shop front or inside a forum thread. The first has an incentive to overstate; the second is hard to verify. This site exists to hold the boring, comparable facts in one place, with the strength of the underlying evidence stated plainly next to every claim.
Non-commercial status
PeptideIndex does not sell peptides, does not take advertising from peptide vendors, and does not use affiliate or referral links. No supplier, clinic or product on this site is endorsed, and suppliers cannot pay to be listed, ranked higher, or removed.
Supplier price pages exist to make publicly advertised prices comparable — normalised to USD and to price per milligram. Inclusion of a supplier is not a quality, safety or legality judgement.
How information is sourced
Compound profiles are compiled from published peer-reviewed literature, regulatory and manufacturer documentation where a compound has an approved form, and — clearly labelled as such — commonly reported non-clinical protocols. References are listed on each profile page.
Price data is collected from suppliers' own public product pages and, where a supplier publishes structured product data, from that feed. Every published price records the date it was checked. The collection and review process is described on the price methodology page.
Videos in the index are third-party YouTube content. They are indexed and classified, not produced or endorsed by this site.
How the database is maintained
The compound database and guides are maintained as versioned content in the site's own codebase: a change to a profile is a change to that file, not an untracked edit. Price data is refreshed by an automated collector whose results pass a manual review queue before publication.
Corrections are applied in the source content as soon as they are identified and verified, and the corrected page ships with the next deployment. Where a correction materially changes a safety-relevant statement or an evidence grade, the page text says what changed rather than quietly overwriting it.
Authorship
Content on this site is published at organisation level under the name PeptideIndex. There is no named individual author, no medical reviewer, and no clinical staff behind it, and nothing here should be read as having been reviewed by a clinician. That is stated plainly rather than dressed up, because the alternative — inventing credentials — is exactly the behaviour this site was built to avoid.
Limitations you should assume
Most compounds described here are not approved for human use. Much of the underlying research is preclinical, in animals, or in small short-duration human trials. Long-term safety data is usually absent entirely.
Dosing figures are descriptive summaries of what appears in the literature and in commonly circulated protocols. They are not prescriptions and they are not a recommendation to use anything.
Legal status varies by jurisdiction and changes. Prices change daily and may be out of date the moment they are published; always check the supplier's own page before acting on any figure here.
How to read this site
Start with the evidence grade. 'Strong' means well-replicated human trial data; 'Limited' means the claim rests on very little. Treat the grade as more important than the length of the benefits list.
Then read the considerations and side effects before the benefits. Then, if anything here matters to a decision you are making, take it to a qualified clinician and verify it against the primary sources cited.
