Research materials carry responsibility. We sell for laboratory research use only, we say so everywhere, and we decline to describe our products in the language of medicine. No claims about treating anything. No dosing guidance. No outcome figures.

That position costs us marketing copy that competitors use freely, and we accept the trade. It also shapes what we will not do: we do not market to anyone under 21, we do not sell into restricted destinations, and we decline orders that read as intended for personal use.

It shapes labeling too. Every vial carries its lot number, every lot has a certificate from an independent laboratory, and the certificate we publish is the one the laboratory issued. If we cannot back a line with a certificate, we do not print it.
