It names your lot.

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.

  • Kevin O.Jul 10, 8:27 AM

    Third order. Consistency between batches has been excellent and the 20mg option is great value.

  • Sam W.Jun 24, 8:27 AM

    Fast turnaround — ordered Monday, arrived Thursday. Vials look professionally done.

  • Rafael OkonkwoJun 15, 7:06 PM

    Arrived cold, double-sealed, lyophilized cake fully intact. Ran it on our LC in-house and identity confirmed. Exactly what the label said.

  • Anders KjelstrupJun 2, 7:26 AM

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

  • Renee L.May 30, 8:27 AM

    Quality is there. Wish shipping was a touch faster but everything arrived intact and cold.

  • Halden PikeApr 30, 5:04 PM

    Cold pack was still frozen on arrival. Cake reconstituted instantly. This is how research material should ship.

  • cryo_kestrelMar 27, 7:13 PM

    Third lot of 209-RT-GLP3 from these folks and the batch-to-batch consistency is the reason I stopped shopping around.

Questions

What exactly am I purchasing?

209-RT-GLP3 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.
