Quality

Third-party testing and lot documentation

Purity data is the only claim we make. Every lot is released against independent analytical testing and shipped with documentation you can file against your own records.

Step 1

Incoming identity check

Each incoming lot is sampled and screened by mass spectrometry to confirm the molecular mass matches the declared sequence before it is accepted into inventory.

Step 2

HPLC purity quantification

Reverse-phase HPLC quantifies purity as an area-percent value. Lots that fall below the catalog specification for a listing are rejected, not re-graded.

Step 3

Appearance & moisture review

Lyophilized cake appearance, residual moisture, and vial seal integrity are inspected and recorded against the lot record.

Step 4

Lot-matched documentation

The certificate of analysis references the exact lot number printed on your vial, including test dates, method, and the issuing laboratory.

Boundaries

What a certificate of analysis does not say

Analytical testing describes chemistry. It never establishes suitability for use in or on a person or animal.

  • No dosing, protocol, reconstitution-for-use, or administration instructions
  • No sterility or pyrogen-free claim for human or veterinary administration
  • No representation that any material is a drug, supplement, food, or cosmetic
  • No comparison to, or implication of equivalence with, any FDA-approved product
