02 / The assay

It names your lot.

Every batch is third-party tested and named by its lot number — the same lot printed on the vial in your hand. This vial ships from lot 2026, tested by Janoshik Analytical.

Quality

Released by the lot.
Never by the batch average.

A batch average hides the outliers. We publish the number for the lot you actually receive — matched to the code on your vial — so the paperwork describes your material, not a favourable mean across a production run.

03/ Protocol & terms

Handling

Store lyophilized vials at −20 °C, protected from light. Reconstitute with bacteriostatic water and keep the solution refrigerated at 2–8 °C.

Dispatch

Orders placed before the daily cutoff ship same or next business day, discreetly packaged. Tracking is emailed on dispatch.

Guarantee

Every lot ships with third-party analytics. If a vial arrives damaged or a lot fails to match its COA, we replace it — see our refunds policy.

    COA matched the vial to the decimal — HPLC trace was clean, no shoulder peaks. Reconstituted crystal clear in bac water. Reordering.

  • Freya LindqvistMay 13, 6:03 AM

    Assayed on-spec. Cold chain held. Would've given five if the tracking updates were a bit more frequent.

  • Estelle VandermeerApr 28, 7:38 PM

    Third lot of 209-GLT from these folks and the batch-to-batch consistency is the reason I stopped shopping around.

Questions

What exactly am I purchasing?

209-GLT is supplied strictly as a reference material for in-vitro and laboratory research. It is not a drug, supplement, or medical product, and nothing on this page describes human or veterinary use.

How should this be stored and reconstituted?

Store the lyophilized vial at −20 °C away from light. For research reconstitution, bacteriostatic water is the standard diluent; keep the reconstituted solution refrigerated at 2–8 °C.

Is this material third-party tested?

Yes. Batches are analysed by an independent laboratory. The lot number on your vial matches the certificate of analysis published on our COA index, so you can verify the exact material you received.

How is my order shipped?

Orders placed before the daily cutoff ship same or next business day in discreet packaging. A tracking number is emailed to you when the parcel is dispatched.

What is your return policy?

If a vial arrives damaged, or a lot does not match its certificate of analysis, contact us for a replacement. Full terms are on our refunds page.
