Lookalike domains are common in research peptide sales. PeptidesGrid checks every store domain it knows against the websites Finnrick Analytics lists for each vendor. On Sep 25, 2026 it had checked 185 domains: 153 Finnrick-listed, 24 not Finnrick-listed, 1 listed for 2 vendors, and 7 with a fraud warning from a named source.
This is the longer version of the six checks on the fraud warnings page. They lower the risk but don't remove it: a Finnrick-listed domain is not an endorsement, and a domain missing from the warnings page isn't safe for that reason alone.
1. Look the domain up
Type the domain into the search box at the top of any page, or browse the domain check list. Every domain the site knows has its own page with one of four results:
- Finnrick-listed: Finnrick lists the domain for the vendor that runs it, or a listed domain points to it.
- Not Finnrick-listed: the store uses a vendor's name on a domain Finnrick doesn't list for it, or isn't tied to a scored vendor. It may still be an older or second site of the same business.
- Listed for 2 vendors: Finnrick lists the domain for more than one vendor, and it isn't clear which runs it.
- Fraud warning: a named source warns against buying from the domain. The page quotes the warning with its date and links to the source.
A domain the site doesn't know hasn't been checked; carry on with the steps below.
2. Compare letter by letter
Finnrick's note on Paradigm Peptide, fetched Sep 25, 2026, puts it plainly: "check carefully that you are buying from the web site of this vendor and not from unaffiliated sites with almost the same URL." The warnings in the site's data show the common patterns:
- Letters added, plus extra words. Finnrick lists orbitrexpeptide.is and orbitrexpeptide.com for Orbitrex Peptides. Its note on the vendor, fetched Sep 25, 2026, says: "Only shop from the official address, and not from orbixtrexpeptideco.com or orbitrextpeptidelab.com". The first inserts an "x" (orbixtrex) and adds "co"; the second adds a "t" (orbitrext) and the word "lab".
- A different ending. Finnrick lists glbiochem.com for GL Biochem and ggpeps.com for Nantong Guangyuan (GYC). Its notes on those vendors, fetched Sep 25, 2026, say "DO NOT purchase from glbiochem.net" and "DO NOT purchase from ggpeps.net". The name is identical; only .com became .net.
- A dropped hyphen, an extra word, a country ending. Finnrick lists royal-peptides.com for Royal Peptides. Royal Peptides' own site, checked Sep 25, 2026, says: "Domains such as royalpeptidesusa.com and royalpeptides.ca are not affiliated with Royal Peptides." The first drops the hyphen and adds "usa"; the second drops the hyphen and ends in .ca.
- An unfamiliar ending. Finnrick's note on Shanghai Sigma Audley (SSA), fetched Sep 25, 2026, says "DO NOT purchase from sigmaaudley.site".
Also watch for one letter missing, doubled or swapped, a plural "s" added or dropped, and words such as "official", "usa", "lab" or "shop" added to the name. Check subdomains too: in shop.examplepeptides.com.other-site.net, the domain that matters is other-site.net, the part just before the ending.
3. Check what the vendor names as official
Many vendors publish a page listing their real domains, and some list domains that are not theirs, as Royal Peptides does. Find it through a source you already trust, such as the vendor's Finnrick profile or the vendor page on this site, which links its Finnrick-listed store, not through the domain you are checking.
Also check that the brand is still trading. Finnrick's note on Peptide Sciences, fetched Sep 25, 2026, says: "On 6 Mar 2026, Peptide Sciences announced it stopped trading. Further purchases from this brand are fraudulent." The fraud warnings page lists stores that have announced they are closing or have closed.
4. Look for a copied catalog
A second domain with the same product photos, prices, descriptions and policy text as a known store is a warning sign, even when the site looks professional. Search for a distinctive sentence from a product description in quotation marks and see how many domains carry it. A domain age lookup (WHOIS) shows when a domain was registered; a very recent registration using an established name deserves extra care.
5. Be careful with crypto-only payment on a new domain
Card payments can sometimes be disputed through the card issuer. Crypto payments and most bank transfers can't be reversed. A site that takes only crypto and appeared recently is a higher risk, because there is no way to recover the money if nothing ships. If a chat or email asks you to pay a different wallet or account from the one at checkout, stop and confirm through a channel you already trust.
6. Tell the next buyer
If a site took your money and sent nothing, report it here with your evidence, such as the order confirmation and payment record. Moderators review every report before it is published, and evidence files are seen only by moderators. A report about a domain the site didn't know creates a page for it once approved. Stores can respond to or dispute any report.
The site keeps a dated copy of every page a warning relies on. If you run one of these domains and think a warning is wrong, ask for a review.
Warnings are quoted from the named sources with the date checked; PeptidesGrid has not tested these sites itself. Last reviewed Sep 25, 2026.
