02 / The assay
Every batch is third-party tested and named by its lot number — the same lot printed on the vial in your hand. Current lot documentation is published on our COA index.
Quality
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
Store lyophilized vials at −20 °C, protected from light. Reconstitute with bacteriostatic water and keep the solution refrigerated at 2–8 °C.
Orders placed before the daily cutoff ship same or next business day, discreetly packaged. Tracking is emailed on dispatch.
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.
Does what it should — consistent results across my replicates. Packaging was minimal but the vial was intact.
Cold pack was still frozen on arrival. Cake reconstituted instantly. This is how research material should ship.
Arrived cold, double-sealed, lyophilized cake fully intact. Ran it on our LC in-house and identity confirmed. Exactly what the label said.
209-SMX 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.
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.
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.
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.
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.
