Why this site asks you to confirm your age and your research context before entering.
Awaiting legal reviewThis wording states EVOHN’s current position and has not yet been approved by a qualified adviser in the relevant jurisdiction. It is published for transparency and must not be relied upon as legal advice.
Before the catalogue is shown, the entrance notice asks you to confirm two things: that you are at least 18 years of age, and that you are accessing the site in a research, laboratory or professional capacity rather than seeking material for personal use.
The compounds described here are supplied for laboratory research only. They are not medicines, they are not approved for human or veterinary administration, and presenting them to a general audience without that context would be misleading.
The notice is an honest statement of who the catalogue is for. It is a declaration you make, not an identity check — EVOHN does not verify the declaration and does not collect any document from you.
Your acknowledgement is written to your own browser's local storage so the notice is not repeated on every page. Nothing is transmitted to EVOHN. Clearing your browser data restores the notice on your next visit.
Declining the notice returns you to a page explaining the position and does not open the catalogue. There is no penalty for declining and no attempt to ask again in a different form.
A self-declaration is not an age-assurance system and is not represented as one. Whether it is sufficient in a given territory — and whether a stronger mechanism is required — needs confirmation by a qualified adviser.
