Built on transparency.

Every batch is independently verified for identity, purity, endotoxins and heavy metals, with batch-specific documentation supplied for complete transparency.

How It Works

Every batch,
assessed on its own merits.

We don't rely on generic paperwork, recycled certificates or supplier claims alone. Every batch is independently tested by Janoshik — the most trusted independent testing lab in the industry — and every result is verifiable directly on their site, not just ours.

  • 01

    Independent Verification

    Every batch is tested by Janoshik, an independent laboratory with no stake in the result — not assessed in-house, not self-certified.

  • 02

    Batch-Specific COAs

    Every Certificate of Analysis relates to a single production batch, with full traceability — never a reused or generic document.

  • 03

    Controlled Handling

    Stored, handled and dispatched under controlled procedures from intake through to release — not just tested once and forgotten.

What every batch is tested for

  • HPLC purity analysis, typically 99%+
  • LC-MS identity confirmation
  • Endotoxin screening on every batch
  • Heavy metal screening on every batch
  • Unique batch reference assigned
  • Batch-specific Certificate of Analysis

Every result above is independently verifiable — not just claimed.

Certificate of Analysis

Select a compound to view its batch-specific Certificate of Analysis, including independently verified identity, purity, endotoxin and heavy metal testing.

Clear data,
not vague claims.

A purity percentage on a listing page is a claim. A batch number you can search on an independent lab's own database is data. That's the difference this page is built around — and it's why every step on the right is something you can check yourself, not just take our word for.

How to verify a batch yourself

  1. 1 Find the batch number on your vial label or Certificate of Analysis.
  2. 2 Search that batch number on Janoshik's verification page.
  3. 3 Compare the result against the COA you were sent.
  4. 4 If anything doesn't match, contact us before using the product.

Verification doesn't end
after dispatch.

Every batch remains supported by its Certificate of Analysis, handling guidance and batch documentation after dispatch.
