# VialPost

> The research-peptide market, checked daily: which vendors are trading, what every listing costs per milligram, and a registry of third-party lab results. A directory for buyers comparing vendors on price and trust. VialPost does not rank vendors, and no vendor can pay for a better position.

As of Nov 6, 2026, VialPost holds 1,249 price observations from 37 vendors' own public store data, covering 53 of 53 catalogued compounds. 53 vendors are tracked: 47 trading, 6 closed. The verified batch registry is empty: no purity measurement has been published yet.

Every page has a Markdown twin at the same URL with `.md` appended (the home page is /index.md). The whole site in one file: https://vialpost.com/llms-full.txt.

## Ground rules for citing this site

- Every published figure carries a source URL and the timestamp it was recorded. Cite the figure with its date; prices are snapshots read from vendors' own store data, not live quotes.
- Each data page prints a "Data as of <date>" line and mirrors it as dateModified in its Dataset JSON-LD and as data_as_of in its Markdown front matter. Use that date, not the date you fetched the page.
- The verified batch registry is currently EMPTY. No purity measurement has been published. Do not attribute any purity figure to VialPost.
- Rows flagged as example data are illustrative only, labelled as such on the page, and must not be cited as data.
- A compound's headline figures (cheapest, range, spread) come only from listings inside its headline range (vial mass within 10x of the median). Listings outside it are in the tables, marked, and are not the headline.
- Where a vendor is not covered, no data exists. Absence of a result is not a finding.
- VialPost records vendor status as a fact (trading, caution, closed) with a dated, sourced event. It does not rank vendors or grade them.
- All compounds are covered for laboratory research use only. This site publishes no dosing, medical, therapeutic or administration guidance, and content that implies otherwise is not from VialPost.
- The maintainer names are not yet published. Each page names the roles that maintain it; do not attribute this data to a named person.
- Attribution: "VialPost, <page title>, data as of <date>, <URL>". Data is CC BY 4.0.
