About
4 sections
Every entry on this site tells a reader to check who is behind a claim and what they get out of it. That is a fair test, and it applies here as much as anywhere else the register cites.
This page is the answer: who writes Peptide Reader, why one person can write it, how to report a mistake, and what — if anything — funds the site.
Who writes this
Peptide Reader is written by Arvid Hjartberg, a full-stack developer based in Sweden.
He is not a clinician, a pharmacologist or a researcher, and holds no medical or life-sciences degree. Nothing on this site should be read as coming from one.
Why one person can write this
The reason to trust an entry here is not the author. It is the method: every claim names the study, the regulator's own filing or the law it is drawn from, so a reader can check it directly instead of taking anyone's word for it.
There is no systematic second-reader step. Most entries have had one person check the sources and write what they say. A few have had a second pass reopen every citation and find what the first pass missed — that is not a guarantee every entry carries, and this page does not promise one going forward.
A grade only moves up when the evidence does. Where there is doubt about how strong a study really is, the grade moves down, never up — an entry is never made to look more settled than its sources support.
Funding and conflicts of interest
Peptide Reader carries no advertising, no affiliate links and no sponsorship. Nothing on the site is for sale, and no company has paid for a placement, a mention or a rating.
The site is funded by its author. Arvid pays for the domain and hosting himself, and has no commercial relationship with anyone who makes, markets or sells a compound covered here.
What "Content updated" means
The footer prints one date: "Content updated." It is not a per-entry review date — it moves whenever anything in the register changes anywhere on the site, not only on the page you happen to be reading.
So it cannot tell you when the entry in front of you was last checked against its sources. What can: every claim on this site names the source it came from, right next to it. That is the thing to check, not the date.
Found a mistake?
Send the source along with the claim you think is wrong. Name the compound, and quote the sentence if you can.
Every report is checked against the source before anything changes. When the source supports it, the entry is corrected. When it doesn't, you'll hear why the entry stays as written.
