About PeptideX

You probably landed here after looking up one specific peptide — something a podcast, a gym friend or a forum thread brought up — and hit a wall of sellers, before-and-after photos and confident posts that flatly contradict each other. This site is what was missing from that search: a plain, sourced answer, with nothing to sell you.

If this sounds familiar

You read that a peptide heals injuries, melts fat or sharpens memory. You go to check it, and the top results are shops. The reviews are glowing and anonymous. One page calls it “clinically proven”; another, three clicks away, says it did nothing in the only human trial it ever had. An approved medicine and a powder that has never been tested in a person sit side by side, described in the same breath and the same confident tone. And the one question you actually came with — does this work, and is it safe? — is the one nobody without something to sell seems to have answered.

That gap is the whole reason this exists. It began as a private set of notes: opening the papers one at a time and writing down what they actually said, so the well-studied handful could be told apart from the great many that have nothing behind them but a product page. Those notes became 174 entries. Publishing them costs nothing and the same questions keep coming, so here they are.

Why the search looks like that

It is not a conspiracy, it is economics: a seller has a reason to publish about a compound, and almost nobody else does. But it bends everything that gets written in one direction. Weak evidence becomes “promising research”. One uncontrolled study in nine people becomes “clinically studied”. A dose that circulates on forums becomes “the standard protocol”. No single line is quite a lie, and the overall picture is still wrong — because the one thing a seller will never write is there is no good reason to think this works.

That sentence is true of a large share of the compounds documented here, so this site writes it.

What you get instead

A straight answer for each compound: how it is meant to work, what the research actually shows, and — plainly — when the honest verdict is “unproven” or “nobody knows”. And you do not have to take any of it on faith.

• Every claim shows its source. 3,912 inline citations across the entries point to 1,047 references and 821 distinct sources. A superscript number is a link — click it and read the paper yourself.
• “Nobody knows” is written down as exactly that. 44 entries are marked short because there is genuinely almost nothing published. An empty dosing section means no credible figures exist — not that they were left out.
• Numbers come from the document, not from other websites. Doses and trial results are read out of the official product information or the paper itself; where a widely repeated figure disagreed with its own source, the source won.
• The links are checked by machine. Every reference URL is fetched automatically, so a citation that has quietly rotted — or was never real — is caught rather than left to sit there looking authoritative.

What it will not do

No suppliers, no prices, no affiliate links, no advertising — and no arrangement under which any of those could appear. Nothing is ranked or recommended, and there is no “best peptide for” anything. Having no commercial interest in any compound is the only reliable guarantee that there is no reason to describe one generously. More on that.

It also will not tell you what to take. Doses are reported as part of an honest description of what has been studied, not as instructions — many compounds here are not approved for human use anywhere, and several have documented harms. That decision belongs with a doctor who can see your bloodwork, which this site cannot.

Why there is no name on it

A byline on a health page is worth something only if you can check the person behind it, and usually you cannot. So instead of asking you to trust an identity, this site is built to make trust unnecessary: the citations, the machine-checked links and the stated gaps above are all things you can verify without knowing who wrote them. The argument is not “trust this” — it is you do not have to.

Where it falls short

Worth knowing before you lean on it. Entries are only as current as their last edit, and product information changes. A few claims stay unsourced and are marked that way, usually because the underlying register is not publicly reachable. And for the obscure compounds the honest answer is often that nobody knows — unsatisfying, but it is the finding.

If something here is wrong, it is worth flagging: the content lives as plain JSON files, one per compound, so a correction is a small change to a single file.
