About

What we stock, what we commit to, and what we deliberately do not claim.

What we do not claim

There is no purity percentage anywhere on this site, no certificate of analysis, no named third-party laboratory and no batch testing programme. That is because we do not currently run one, and a supplier who publishes numbers they cannot stand behind is worse than one who publishes none.

There are also no customer review counts, no star ratings and no stock-scarcity timers. In this category those are the standard furniture of sites that are not what they appear to be, and a site that looks like those is asking to be read as one.

If certificate-backed material is what your work requires, that is a legitimate requirement and this is not currently the right supplier for it. Saying so costs an order and is still the correct answer.

Terms of supply

All products listed are sold strictly for in-vitro laboratory research and analytical use. They are not drugs, foods, cosmetics or medical devices, and are not intended to diagnose, treat, cure or prevent any disease.

The full explanation of what that means is set out in the reference section, including the distinction between research material, compounded preparations and approved medicines, which are three different categories rather than three grades of one thing.

Questions

Do you publish certificates of analysis?

Not at present. Rather than imply a testing programme that is not in place, the site says so plainly. What is committed to instead is operational: dispatch times, unbranded packaging, a reship guarantee, and answers from a person inside 24 hours.

How many compounds do you stock?

89 research compounds plus laboratory supplies, organised by mechanism, by research area and by format so the same compound can be found from whichever direction you approach it.
