Like-for-like prices

What we found at Swiss Chems
The only vendor in our index with an FDA warning letter on file, a removed Trustpilot profile, and a BBB 'F' at the same time. The certificates are real Janoshik reports and the prices are clear, which is why it still scores four points — but the letter, the unanswered complaints and the returns policy that contradicts its own product pages are the facts a buyer should weigh first.

nine complaints, unanswered (non-delivery, refund refusal).
Some third-party sites still quote a ~4.2 score that no longer exists anywhere checkable.
the certificate PDF's text could not be extracted from outside.
the site, the FDA letter and the BBB all use the trade name only, and the BBB lists a different (Dover, DE) address on the same phone number.

Trustpilot profile REMOVED. BBB rates the business F with nine unanswered complaints.

What did Finnrick Analytics find when testing Swiss Chems products?
Finnrick Analytics tested 9 samples across 3 Swiss Chems products. BPC-157 received a C (Okay) rating across 2 tests. Ipamorelin received a D (Poor) rating across 4 tests. CJC-1295 received an E (Bad) rating across 3 tests — with an average score of -0.9, indicating that essentially no active compound was detected in the tested samples. These are independent third-party lab results, not vendor claims.
Is Swiss Chems actually based in Switzerland?
No. Despite the Swiss branding, Swiss Chems is a US-based operation. The company was founded in 2018 and fulfills orders from within the United States. The Swiss name appears to be a marketing choice rather than a reflection of the company's actual location or manufacturing standards. US domestic shipping typically takes 3–7 business days.
Does Swiss Chems sell SARMs?
Yes. Swiss Chems sells SARMs (Selective Androgen Receptor Modulators) in addition to peptides and other research chemicals. This broader catalog may appeal to researchers who want a single vendor for multiple compound categories.
