Legal, quality & shipping.
"Research Use Only" designates substances intended exclusively for scientific, analytical and laboratory-chemical investigations. They are not a medicinal product, not a dietary supplement and not intended for use in humans. All substances offered on this website fall into this category.
Purchasing research chemicals for scientific purposes is generally permissible in Germany. Our substances are subject neither to the Narcotics Act (BtMG) nor the Medicinal Products Act (AMG), as long as they are not intended for use in humans. The buyer is obliged to independently check the legal regulations applicable in their region.
Every batch is tested for ≥99 % purity by an independent, accredited laboratory — including Janoshik Analytical — via HPLC-MS (high-performance liquid chromatography with mass spectrometry). The Certificate of Analysis (COA) is available as a PDF on every product page and contains the batch number, measurement method and purity value.
Shipping takes place within 24–48 hours from Germany in neutral, discreet packaging — with no inference about the contents or the sender. We deliver to Germany, Austria and Switzerland.
Lyophilized powder is best stored before reconstitution at −20 °C, protected from light (stability: up to 24 months). After reconstitution with sterile water, the solution should be kept at 2–8 °C and used within 30 days. Information applies exclusively to research purposes.
Yes. On every product page you will find the lab certificate of the current batch as a preview and PDF download — with purity, method, batch number and issue date. Transparency without reservation.
