A traffic-calibrated estimate for a frozen worldwide panel of 995 research-use-only peptide storefront domains, based on 47.75 million estimated visits in May–July 2026.
Disclaimer: Each domain’s gross sales figure is a model estimate using the same traffic-to-sales coefficient. Individual storefront revenue has not been verified.
How we estimate $4.31 billion in annualized gross sales
The panel and registration records were frozen on August 22, 2026. This full census extension was prepared on October 2, 2026.
The covered domains received 47,750,538 estimated visits in May–July 2026. PeptidePrices applies 0.119778782 accepted orders per estimated visit and a $188.518369 reference order value. The retained rounded product is $22.580501 per visit. Multiplying that coefficient by the estimated visits and four gives $4,312,924,284.24.
Traffic
Similarweb public-facing estimates retrieved through the community sourabhbgp/similarweb-scraper extractor. The monthly totals are 15,632,799 in May, 15,461,993 in June and 16,655,746 in July.
Conversion
Six storefronts with matched traffic and authenticated order evidence. Sequential order growth receives vendor-specific terminal rejection adjustments; direct paid-sales totals receive no second rejection adjustment.
Order value
The six-store reference median was checked against fourteen storefronts. Each storefront contributes one order-value point to the equal-store checks.
Scope
A worldwide panel of 995 research-use-only (RUO) peptide storefront domains. A domain is not a separately identified company. Uncovered traffic and 91 unresolved registration dates remain unknown.
Gross sales
Modeled accepted consumer order value (called GMV in the dataset), with heterogeneous treatment of later refunds, chargebacks, shipping and taxes. Fourfold annualization projects the May–July run rate.
Traffic error, the small conversion panel, sequential-order assumptions and a common coefficient across storefronts affect the estimate. The model has no full uncertainty interval.
Explore the conversion and order-value assumptions
Scenarios hold the frozen traffic and fourfold annualization fixed. They show assumption sensitivity; they do not estimate a statistical confidence interval. The revenue-per-visit coefficient is rounded to six decimal places, as in the retained model.
A fragmented market needs a common reference point
The research-peptide storefront market has a long tail. In our 995-domain panel, the largest domain received 3.299% of estimated visits in May–July 2026; the ten largest together received 18.381%. Most of the panel's traffic was spread across hundreds of smaller storefronts.
New storefront identities can emerge quickly alongside longer-established businesses. Of the 904 domains with a resolved registration date, 465 (51.4%) were less than a year old at the August 22, 2026 snapshot. Domain age measures the registration, rather than how long its operator has sold peptides.
PeptidePrices brings prices, seller profiles and laboratory records into a common research workflow. The frozen census gives those changing storefronts a dated reference point, while the live tools show current listings and evidence.
No small group of storefronts defines the covered market
PeptidePrices mapped 995 storefront domains representing 47,750,538 estimated visits from May through July 2026. The long tail explains why researchers otherwise have to locate and interpret pricing, availability, vendor information, and laboratory records across hundreds of sites.

What a COA is—and why the laboratory matters
A Certificate of Analysis is useful only when its source stays visible
A Certificate of Analysis, or COA, is a laboratory report describing results for a submitted sample. Researchers use these reports to examine fields such as the tested compound, reported purity or quantity, test date, report number, and issuing laboratory when those fields are available.

Our methodology
How we built this report
01
Application snapshot
The August 30 directory snapshot contained 103 vendor profiles, 3,294 usable in-stock listings, and 83 priced compounds. Prices and availability can change after the displayed check date.
02
Storefront panel
The 995-domain panel is a frozen, coverage-bounded map—not a legal registry of every seller. Estimated traffic uses one consistent public estimate method across the covered rows.
03
Domain registrations
Registration events came from public RDAP records. The 91 unresolved dates remain unknown and were not assigned inferred values.
04
Certificate identity
A certificate identity and a public source record are different units. Laboratory records, vendor copies, and third-party publisher records retain separate roles.
A laboratory report describing results for a submitted sample.
Certificate identity
One defensibly identified certificate record. It is not a physical vial.
Laboratory-issued
Published by or resolved through the issuing laboratory's own public system.
Vendor copy
A document, image, link, or metadata record published by a seller.
Third-party publisher
A source that republishes or indexes a record but did not issue the certificate.

Frequently asked questions
Peptide market intelligence, explained
Direct answers using the dates, denominators, and source roles preserved in this release.
What is the estimated size of the covered research-peptide storefront market?
PeptidePrices' 995-domain panel has annualized modeled gross sales of $4.313 billion at its May–July 2026 run rate. The model multiplies 47,750,538 third-party estimated visits by a $22.580501 accepted-order value per visit and fourfold annualization. Conversion is calibrated from six storefronts; order value is checked across fourteen.
Where can I download the full peptide storefront census?
The full CSV and JSON downloads contain all 995 covered domains, May, June and July 2026 estimated visits, panel shares, annualized modeled gross sales and available RDAP registration dates. The methodology explains the frozen panel, traffic source, conversion calibration and calculation. Private order records and affiliate terms are excluded.
What is the PeptidePrices Market Intelligence Index?
It is a dated public report connecting three separately measured layers: an August 30, 2026 application snapshot of 103 vendor profiles and 3,294 in-stock listings across 83 compounds, a frozen panel of 995 storefront domains, and a separate database containing 112,713 public certificate identities.
Why does peptide market intelligence matter?
Pricing, availability, seller context, and laboratory records are distributed across many separate websites and public systems. Inside the covered 995-domain panel, the ten largest domains represented only 18.381% of estimated visits from May through July 2026. A common index gives researchers one starting point for comparing those separate signals.
Why does the report show both 103 vendor profiles and 995 storefront domains?
They are different datasets. The 103 vendor profiles belong to the August 30 PeptidePrices application snapshot. The 995 domains belong to a broader frozen seller-market research panel. The two counts answer different questions and are not added together.
Are the prices in this index current?
This release preserves a dated August 30, 2026 application snapshot. The separate live market report is the current product surface, and each listing displays its own check date because price and availability can change after collection.
What is a Certificate of Analysis, or COA?
A COA is a laboratory report describing results for a submitted sample. The August 30 PeptidePrices research database contains 112,713 distinct public certificate identities, with laboratory-issued records, vendor copies, and third-party publisher records retained as separate source roles.
Can the PeptidePrices index data be downloaded and cited?
Yes. PeptidePrices provides public aggregate summaries in JSON and CSV, a downloadable methodology, a stable canonical URL, publication and modification dates, and a recommended citation. The downloads preserve each metric's date, denominator, source class, wording, and limitations.
