Is Swiss Chems legit?
Swiss Chems scores 5.39 out of 10 (Weak, #70 of 100) as of November 2, 2026 and does not meet our testing gate: 27 of the 49 products we score carry a certificate, 22 confirmed with the issuing lab (labs we grade A to B+); 5 of those certificates are vendor-issued or from a source whose independence we could not establish. Its strongest area is operating history (7.6/10), with over eight years of records; its weakest is transparency (2.5/10).
On lab evidence, the heaviest-weighted factor, Swiss Chems has no third-party testing we could independently verify, with COA work on record from Freedom Diagnostics Testing, Janoshik Analytical. The testing gate applies because that testing could not be independently verified (Third-party testing not established); its limit for Swiss Chems is 8.00, and this score is already below it. Its lowest price per milligram in our data is on NAD+ (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 credibility4.6/10
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.

Testing gate: 22 of 49 products have a certificate from a directory laboratory (not tier D, not self-issued) with the key confirmed at the laboratory. That is fewer than half, so the testing cap applies (see the methodology).

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 · 5.50to5.39
Lab evidence re-checked on 2 November 2026 after our ranking review of 26 October. The newest certificate for each product was confirmed at the issuing laboratory, adding Freedom Diagnostics Testing or Janoshik certificates for Melanotan II, Tesamorelin, DSIP, Glutathione, MK-677 and HCG. Sixteen products the store sells were missing from our list and now count under our coverage rule; seven of them have no certificate and three carry vendor documents that name no laboratory. Certificates confirmed at a laboratory cover 22 of 49 products, below the half needed to lift the testing cap. Lab 4.8 to 4.6.
- Audit · 5.48to5.50
Pricing recomputed on 26 October 2026: a vendor was removed from the directory, which moved the market median for the same products: pricing 6.9 to 7.0.
- Audit · 5.50to5.48
Pricing recomputed on 26 October 2026: listings added for a newly reviewed vendor (Lotus Peptide) moved the market median for the same products: pricing 7.0 to 6.9.
Earlier audits (9)
- Audit · 5.00to5.50
Lab score recalculated on 22 October 2026 under the published core-product rule (A1b): a missing certificate on one of the 15 most widely carried products still counts fully, while on any other product it now counts at half weight, so a broad catalogue is not penalised as much for its breadth. Lab 3.9 to 4.8.
- Audit · 4.99to5.00
Operating history re-checked on 22 October 2026 under the published rule (earliest dated evidence of the business, including a never-parked store domain and the named operating company, looked up for every vendor): operating history 7.4 to 7.6.
- Audit · 5.16to4.99
Re-scored on 22 October 2026 under version 2 of our published rules. Sermorelin's only document is a heavy-metals screen, which is not a certificate of identity or purity, so the product now scores 0; the MOTS-c and ARA-290 documents name no laboratory and now score the flat 2.0 that applies to every certificate whose source cannot be established. The testing gate is now computed from the certificates: 16 of 33 products have a certificate confirmed at a directory laboratory, fewer than the half required, so the testing cap applies; it sits above the weighted score, so it does not lower it. Lab 4.2 to 3.9. Score 5.16 to 4.99.
- Audit · 4.93to5.16
Lab deductions independently re-verified from primary sources on 22 October 2026; a deduction that could not be confirmed was removed or reduced. Lab 3.8 to 4.2.
- Audit · 5.54to4.93
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. shipping and refunds 7.0 to 6.5, pricing 8.5 to 7.0, operating history 8.5 to 7.4, transparency 7.0 to 2.5.
- Audit · 5.65to5.54
Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: every listed product was rescored on the same fixed certificate points, with fixed deductions for certificates more than 12 months old, site statements about testing that the certificates do not bear out and certificates ordered by a supplier or issued to another business. Lab 4.0 to 3.8.
- Audit · 4.99to5.65
Lab evidence re-checked on 20 October 2026 under our coverage rule, which counts a listed product with no published certificate as zero in the lab average. Certificates cover 19 of the 33 products we list that the vendor offers for sale. Lab 2.8 to 4.0.
- Audit · 6.16to4.99
Lab 4.8 to 2.8 and tenure 10 to 8.5. We re-read the certificates behind each listed product under our published rule, which averages the lab score over the products we list and counts a listed product with no certificate as zero. Six products carry Freedom Diagnostics reports confirmed on the laboratory's own site, several carry Janoshik reports we could not check there or vendor documents naming no laboratory, and 16 of the 33 products we list have no certificate. Tenure was aligned to the company's 2018 start, about eight and a half years ago, rather than the top band for businesses over ten years.
- Audit · Verified, no change
Three ranking reviews flagged a likely rise from a 94-report test library. Reading the certificates rather than counting them: no purity figure appears on either one examined, only identity and net content, and the peptide certificate is issued to a supplier called IMT rather than to Swiss Chems. The documents examined were found at the issuing laboratory, but they did not support a higher lab score at that time.
Editor’s notes
Swiss Chems has operated since 2018. Its test library holds certificates from several laboratories. In May 2026 the vendor published an offer to refund an order if independent HPLC testing showed a product below its stated purity. On 2 November 2026 its library listed 132 reports, many of them for non-peptide products, and the store sold 49 of the products we list. For 22 of them we confirmed the newest certificate at the issuing laboratory: 16 Freedom Diagnostics Testing reports that match the laboratory's own copies, among them TB-500 (99.08%), Ipamorelin (99.96%), NAD+ (99.89%), Glutathione (99.74%) and Tesamorelin (99.15%), and 6 Janoshik reports, for CJC-1295, KPV, the BPC-157/TB-500 blend, Melanotan II, DSIP and HCG. Some Freedom reports name Swiss Chems as the client and others a client called IMT, and the reports for capsule products such as 5-Amino-1MQ, Tesofensine, SLU-PP-332, Dihexa and MK-677 show identity and content but no purity figure. MOTS-c, ARA-290, Kisspeptin-10, Oxytocin and Thymosin Alpha-1 carry vendor-branded certificates that name no laboratory, and the Sermorelin document is a Janoshik heavy-metals screen with no identity or purity test. None of the certificates we recorded covers endotoxin or sterility. Semax, Selank, the GHRP peptides, Hexarelin, most bioregulators, Follistatin 344, Gonadorelin, PEG-MGF, LL-37, Adipotide, P21 and Pinealon had no certificate.
