The certificate itself is linked below, is in the product images above, and a copy ships with the vial.
Every lot goes to an independent laboratory before it reaches us, and we test it again when it arrives. Two results have to agree before a compound earns a listing. The paperwork belongs to the exact vial you were sent — not to a representative batch from an earlier run.

The kits
Some things are better together.
Our kits are the combinations worth running together — assembled deliberately, priced below the sum of their parts, and shipped as separate vials so every compound keeps its own lot number and its own certificate.
