Verify your batch
Every vial ships with a lot number. That number pulls up the exact third-party lab report for the batch you received — not a generic spec sheet for the product line.
Great vial, would like more size options. Quality is consistent with what the documentation states. Our only wish is for a smaller 1mg or 2mg option for method development, to avoid opening a larger vial.
Purity report was easy to verify. Batch COA downloadable before checkout, HPLC purity 99.6%. The 5mg cake was intact on arrival and dissolved cleanly for our receptor binding work.
Labelling is excellent. Each vial is labelled with compound, mass, batch and a research-use-only notice. Makes our lab audit trail straightforward. Shipped in a foam insert with a cold pack.
Solid supplier for bench work. Reliable quality across three orders. Would like to see the 10mg size back in stock more often, it sold out twice when we tried to order.
Clean cake, clear reconstitution. The 5mg vial reconstituted fully in under a minute with gentle swirling. No cloudiness. Batch COA showed 99.1% purity and the mass spec trace was included, which we appreciate.
Documentation is the reason we reorder. The COA library being open without a login is a real convenience for our procurement paperwork. Product was as described, 5mg cake, clean reconstitution, batch traceable.
Good product, slow courier. Vial arrived well packed with a cold pack still cool. Reconstituted without issue. Only reason for four stars is the courier took six days to reach us on the west coast; the fulfilment itself shipped the next morning.
Consistent between two batches. Second order from a different lot. Ran our own identity check alongside the published COA and both lots lined up. Labels carry the batch number and a QR to the COA, which saves time when logging inventory.
COA matched the batch on the label. Ordered the 10mg for an in-vitro assay series. The certificate of analysis was already published for the batch printed on the vial, purity reported at 99.4% by HPLC. Lyophilised cake was intact and reconstituted clear in bac water with no particulates.
I had a great experience with this page. The website was easy to navigate, and it had a wide variety of products to choose from. Each item included helpful descriptions and clear ingredient information, which made it easier to compare options.
