Janoshik Analytical is based in the Czech Republic (EU) and accepts samples from anywhere in the world, per their published information. For US customers that means an international shipping leg. Gold Standard Analytics is in Houston, TX — domestic prepaid shipping from all 50 states, or local drop-off.
Janoshik is a real, long-operating laboratory with substantial community trust in the harm-reduction space, and their reports carry QR verification through their own site. As with any lab, judge by verifiability: confirm a report through the issuing lab's official verification page. Every Gold Standard COA resolves in our public registry by accession number.
Per janoshik.com (checked August 18, 2026): the common GLP-1 blind test is $360 and HGH analysis is $500. Per our published pricing: a GLP-1 panel with LC-MS identity, HPLC purity, and net peptide content is $289, and standard research peptides are $189. Always check both labs' current menus — pricing changes.
Both can produce valid results. The practical differences are shipping (domestic 1–4 day transit vs international post plus customs), payment rails, jurisdiction, and how results are verified. If your customers need to verify certificates themselves, prefer a lab with a public, no-login registry — that's how our COAs work.
