Caveats
Purgo Labs: Smaller independent review base than several competitors (80 reviews). The catalog is peptide-focused, so researchers also working with SARMs or broader research chemicals will need a second supplier.
Swiss Chems: FDA warning letter dated 10 December 2024 citing the site's semaglutide and retatrutide pages as unapproved new drugs (both products have since disappeared from the catalog). Trustpilot profile REMOVED. BBB rates the business F with nine unanswered complaints. The FAQ calls Janoshik a 'USA-based laboratory'; product pages promise 30-day returns while the refund policy gives 7 business days and excludes peptides. Sells HCG, HMG and SARMs. No legal entity name.

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.
