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. This vial ships from lot RSP20260325, tested by Janoshik Analytical.
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.
Solid product and honest labeling. Delivery took 4 days to the east coast, packed well.
No complaints on quality. Reconstituted clean, no particulates. Turnaround was reasonable.
Assayed on-spec. Cold chain held. Would've given five if the tracking updates were a bit more frequent.
Third lot of 209-Tesa from these folks and the batch-to-batch consistency is the reason I stopped shopping around.
Spec sheet said ≥99% and our own analysis agreed within margin. Vial fill was accurate too. Impressed.
209-Tesa 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.
