Frequently asked questions.

Lyophilised, research-grade compounds supplied in sealed vials. Where the current lot has been assayed, its third-party Certificate of Analysis is published and linked from the product page; where it is still in testing, the page says so. Products are sold for laboratory and research use only.

Requirements vary by jurisdiction and institution. You are responsible for ensuring your intended research use is lawful where you are. We may request research-use confirmation for certain compounds.

Yes. See our Wholesale page for volume pricing, per-lot COAs, and institutional terms.

An independent third-party laboratory reports purity and identity for the lot it receives, by HPLC-UV coupled to mass spectrometry, and runs a USP <85> endotoxin test in duplicate on lots submitted for it. The lab reports results rather than specification limits, and issues a Pass/Fail verdict for endotoxin only. Every certificate we hold is published in the COA registry.

Visit Certificates of Analysis and enter the batch code printed on your vial, or browse recent batches. Each certificate lists the testing lab and whichever analyses that lot was submitted for.

Lyophilised compounds are dispatched within 48 hours under cold-chain protocols from a temperature-controlled facility. Complimentary shipping applies on orders over $150.

Store lyophilised vials cold and protected from light. See Protocols for reconstitution, storage, and handling guidance.

Yes. Checkout records your order and gives you an order reference. You then pay by a transfer you send yourself from your own account — PayPal, Zelle, Venmo, Apple Cash, Revolut, or a crypto checkout — quoting that reference in the payment memo. The screen after you place the order shows the exact amount and where to send it. Goods are dispatched once the funds clear.

Returns are not accepted once a shipment has been dispatched — opened and unopened vials alike. These are controlled research materials whose temperature history we cannot verify once they have left our custody. There are two exceptions: a shipping error by us, and a vial that does not match the certificate of analysis published for its lot. In either case contact us within 7 days of delivery. See Shipping & Returns for the detail.
