Facility & fulfillment
Every compound arrives with its evidence.
Purity is a claim until it is documented. Kirin treats the Certificate of Analysis as part of the product — not an afterthought.
How we test- 01
Sourced & synthesized
Compounds are produced under controlled conditions and checked against identity specifications before intake.
- 02
Independently verified
Each lot is submitted to a third-party laboratory for HPLC purity and mass-spec identity confirmation.
- 03
Documented & traceable
A Certificate of Analysis is issued per batch and linked to the product, retrievable by batch number at any time.
Look up any batch. Read its Certificate.
Every lot Kirin ships is indexed in the COA Library. Enter a batch number to retrieve the third-party purity and identity results for exactly what you received.
