Is Kyreon legit?
Kyreon scores 7.29 out of 10 (Strong, tied #26 of 100) as of October 22, 2026 and passes our testing gate: all 17 products we score carry a certificate, 17 confirmed with the issuing lab (a lab we grade A). Its strongest area is lab testing (8.1/10); its weakest is operating history (0.9/10), with about four months of records. We also record that its store has not been taking orders since October 22, 2026.
On lab evidence, the heaviest-weighted factor, Kyreon has independently verified third-party COAs, with COA work on record from Freedom Diagnostics Testing. We hold 18 lot certificates in all. Its lowest price per milligram in our data is on Glutathione (see the table below).
How this score was calculated
Every point below follows the published tables in our methodology, with the policy wording we scored and a link to where we read it. Evidence last checked October 22, 2026. Lab credibility is worked product by product from the certificates on file.
Lab credibility8.1/10
Each carried product (lab supplies excluded) is scored from the certificate on file for it, on the published lab rubric: 3 for a published certificate, then points for the laboratory, the verification key, the tests on the certificate and its purity, held to 0 to 10. A certificate that is self-issued, names no laboratory, or comes from a laboratory whose independence is not established scores a flat 2.0; a product with no certificate, a certificate the laboratory’s own record fails, or a posted copy that differs materially from the laboratory’s copy scores 0. Calculated on , the day this page was built; the date each certificate was tested is shown on its row.

Mean of 17 products: 141.5 ÷ 17 = 8.324.
- −0.20LOT Lot numbers that do not identify a single batch (cap −0.2): one lot KR260709A printed on all 18 certificates (17 compounds)
8.324 − 0.200 = 8.124, rounded to 0.1: 8.1/10.
Testing gate: 17 of 17 products have a certificate from a directory laboratory (not tier D, not self-issued) with the key confirmed at the laboratory. That is at least half, so the vendor counts as third-party tested and no cap applies. The store is not taking orders, so the published sub-scores and gate are kept from its last full audit.

Audit history and why the rating changed
We re-audit vendors against their live COAs and site. Here is what most recently moved this rating, and why.
See the full score history and chart
- Most recent audit · 7.31to7.29
The state-registry item (0.5) was removed from the transparency table for every vendor on 22 October 2026. The store is not taking orders, so its other sub-scores stay as audited that day, but the removal applies here too: transparency 6.5 to 6.0.
- Audit · 7.25to7.31
Re-scored on 22 October 2026 under our published rubric for shipping, pricing, operating history and transparency, applied to every vendor the same day: prices re-read from the vendor's site and matched by milligrams per vial, operating history from the earliest dated evidence of the business, and policies scored item by item. pricing 7.5 to 7.9, operating history 1.5 to 0.9, transparency 6.0 to 6.5.
- Audit · 6.65to7.25
Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: an earlier held value was replaced by the rubric's arithmetic; fixed deductions apply for one lot number printed on certificates for different compounds. Lab 7.0 to 8.1.

Editor’s notes
Kyreon's testing is well evidenced. We resolved all 18 of its certificates in the laboratory's own public store rather than reading the vendor's copies, and each lab-held document is byte-identical to the one published on the site. The certificates are issued to Kyreon itself, cover purity by HPLC, identity by mass spectrometry and net peptide content, and report purities between 99.38% and 99.96%. Two things hold it back. Every one of the 18 certificates carries the same lot code, so the lot code does not identify a separate batch for each product, and there is no endotoxin, sterility or heavy-metals testing anywhere. One result is worth singling out: the PT-141 certificate reports 8.11mg of peptide against a 10mg label, about 19% under, which we have noted on that product. Prices were below the market median when we last read them. On 22 October 2026 the website showed a domain parking page instead of its store, so orders could not be placed. The company trades as Kyreon Ltd Co from San Antonio, Texas, and several products use coded names, with retatrutide listed as KYN-3RT, tirzepatide as KYN-2T and semaglutide as KYN-1S. Its domain was registered on 8 July 2026 and the Texas company was chartered the next day, which is what holds the operating-history score down.
