Synthesized in GMP-compliant Swiss facilities with meticulous quality control at every stage of production.
Shipping worldwide to research laboratories. USPS Priority Mail International with DHL Express upgrade available for overseas research labs, with tracking and customs documentation included.
HPLC-verified purity across every product line. Our average sits above 99.8%, with full documentation available per batch.
Every batch ships with a Certificate of Analysis reporting both HPLC purity and mass-spectrometry identity, tied to the lot number on the vial.
Don't just take our word for it. Select compounds — starting with Retatrutide — are sent to Janoshik, an independent analytical lab, and the report is published with a key you can verify yourself.
Most vendors make you request a COA — or show none at all. We publish the manufacturer's Certificate of Analysis for every compound right on its product page: HPLC for purity, mass spectrometry for identity. And for select compounds like Retatrutide, we go further — publishing an independent third-party report from Janoshik with a key you can verify yourself. Nothing hidden, nothing to request.
