Lab tests

Certificates of analysis

Every compound we sell goes through independent third-party HPLC analysis before it ever reaches the catalog, and we keep the results out in the open instead of locking them behind an email opt-in. Each certificate published below is lot-specific — the purity reading, the assay date, and the lot number on the PDF match the sticker on the vial that ships to you, not a generic template recycled across batches. We refuse to ship anything that comes back under 98% on the HPLC trace, and when a batch fails we scrap it rather than re-blend it. The list grows every time the lab returns a new report, so compounds you do not see linked yet are queued for upload as soon as the next round of testing finishes. If a COA you need is still pending, click through to the product page and email us — we can usually share the raw report ahead of the public upload.
