Things you can actually check
- A batch-specific Certificate of Analysis, available before purchase rather than after
- An analytical method stated alongside every figure, not just the figure
- Batch numbers agreeing across vial, box and certificate
- A verification route that checks a code against the manufacturer's records rather than against the packaging
- Stated storage conditions and expiry, with the assumption behind them made explicit
Things that sound reassuring and are not
- A purity percentage with no method attached
- A generic certificate not tied to a batch number
- Claims of a manufacturing standard with no documentation behind them
- Photographs of laboratories
- Reviews and purchase counts, which are trivially fabricated and say nothing about the vial you will receive
The asymmetry underneath
Most buyers cannot analyse what they received. A vial containing nothing at all may never be identified as such, because a null result is easy to attribute to the experiment. That asymmetry is exactly why documentary controls carry the weight they do — and why a supplier whose claims are all unfalsifiable has told you something, if not what they intended.
