The claims this storefront makes
Koi Research Labs LLC, trading as Koi Peptides, says it was founded in 2022 and that its material is “synthesized and lyophilized in the United States” at a partner facility it does not name. Its testing story is more detailed than most. The site describes in-house HPLC and LC-MS before release, a blind retest at an “independent ISO/IEC 17025-accredited laboratory,” USP <85> and <161> endotoxin methods, sterility testing on the About page, and a purity target “at or above 99%.” The FAQ promises a replacement or refund if a peptide does not match its certificate on independent retest, and US orders placed before 2 PM Eastern ship the same day. The catalog is vials, including BPC-157, TB-500, GHK-Cu, Ipamorelin, Tesamorelin, MOTS-c and NAD+, with GLP-class products sold openly under coded names. Prices sit in the middle of the market. The one thing a buyer should know is that the documents check out and the storefront around them is quietly changing shape.
We opened the certificate library, searched it by lot, downloaded the BPC-157 report and read it against its own index entry. We followed the BPC-157 product link to see where it landed, compared the two companies it connected, checked the registered address, read the shipping policy and FAQ, fetched the Trustpilot profile and searched FDA correspondence for the brand and the LLC.
What held up when we checked
The certificate library is the real thing. It sits at koipeptides.com/coa/, it is public, it is searchable by lot, and each entry links straight to a PDF with no login. The published BPC-157 10 mg certificate comes from Freedom Diagnostics and reports HPLC-UV purity of 99.62 percent, LC-MS identity confirmed and net content of 12.14 mg. That is a clean result from a real laboratory, with the identity confirmation by mass spectrometry that many cheaper certificates omit.
The logistics and payment terms are specific. USPS Priority delivers in two to four business days, with UPS 2-Day and Next Day options; shipping is $9.95 flat under $200 and free above, with same-day dispatch before 2 PM Eastern from warehouses in Austin and Long Beach. International shipping is limited to pre-approved research institutions in Canada, the UK, the EU, Australia and select APAC markets. Card, ACH and wire are accepted and a phone number, +1 833-854-9601, is published. A research-use-only disclaimer is present. Three GLP-class listings under coded names are priced from $69.95 to $89.95. The Trustpilot profile shows 3.9 from 32 reviews.
What did not, and what we could not verify
The redirect is the finding a buyer most needs to know about. The BPC-157 product URL on koipeptides.com returns a 301 redirect to kylopeptides.com, which is operated by Kylo Labs LLC at the same 30 N Gould St, Ste R address in Sheridan, Wyoming, with a different phone number. Kylo’s site names Janoshik, Freedom Diagnostics and Vanguard Laboratory as its laboratories. Neither site discloses the relationship between the two brands. The BPC-157 10 mg price of $49.95 is served from Kylo’s domain, and Koi’s own homepage shows BPC-157 at $0.00 in its popular-peptides block. A buyer who clicks a Koi product and pays on a Kylo checkout has no page explaining which company is filling the order.
The laboratory is never named where a buyer would look for it. Koi’s pages say only “ISO/IEC 17025-accredited laboratory.” Freedom Diagnostics appears nowhere on the site except inside the certificate PDF itself, so a purchaser who reads the About page and the FAQ learns the accreditation standard but not who holds it.
The index does not match the document. The library lists BPC-157 lot 2604060200 tested April 7, 2026. The linked PDF is Freedom Diagnostics accession 2605290215, reported May 31, 2026, for a lot labeled “Clear Blue Cap.” Both may be genuine reports, but the entry points at the wrong one, and a lot-searchable library is only useful if the lot you search for is the lot you get.
The address is a mailbox. 30 N Gould St in Sheridan, Wyoming is a registered-agent address shared by many companies, not an operating site; the company’s actual warehouses are described as being in Texas and California. The Trustpilot profile has 7 of 32 reviews at the lowest rating and was merged from other profiles, which makes it harder to read than the headline number suggests.
On what we could not verify: endotoxin and sterility results are claimed on the About page but absent from the published certificate, so both are recorded as unknown. There is no 5 mg BPC-157 price on koipeptides.com; Kylo shows one only at a member price of $19.98. The partner synthesis facility is unnamed, no email address is published, and the catalog size is not stated. No FDA warning letter naming Koi Peptides or Koi Research Labs LLC was found; search hits refer to the unrelated Koi CBD, LLC. No independent aggregator has published test results for this supplier.
Our read
The parts of Koi Peptides that can be checked, the library and the one certificate we read, check out, and they check out well. The parts that frame them do not. A laboratory that is never named on the site, an index entry that points at a different lot’s report, a flagship product that silently hands off to a second brand at a mailbox address, and a $0.00 price on the homepage all suggest a storefront being reorganized without telling its customers.
If you order, verify the lot number on the PDF against the vial before accepting it, because the index has already shown it can point to the wrong document. And before you pay, ask which company, Koi or Kylo, is actually filling the order and which one will honor the retest guarantee. The documents here deserve more trust than the website does.
