Writing this as a caution for anyone researching this space. Ordered from here for laboratory reference purposes and the ordering process was smooth enough, discreet packaging, prompt dispatch. The problems are structural to the entire category and this vendor does nothing to mitigate them: no independent third-party purity verification accessible for my specific batch, vials arrived with labels showing only product codes rather than full composition details, and when I requested certificates their documentation contained inconsistencies in molecular weight listings. Research compounds demand verifiable chain of custody. This supplier does not provide it.
