FAQ

Yes. A sample is drawn from each finished lot and sent to an independent laboratory — the lab that tests is not the facility that produces. Purity is quantified by RP-HPLC against a reference standard and identity confirmed by mass spectrometry. The resulting Certificate of Analysis is published in our COA Library and matched to the lot code printed on your vial, so you can verify the exact material you hold before opening the seal.

These materials are sold strictly for in-vitro laboratory research. They are not drugs, foods, cosmetics or dietary supplements, and they are not intended for human or veterinary consumption or administration in any form. By purchasing you confirm you are a qualified researcher or research institution, aged 21 or over, and that you will handle the material in accordance with all applicable federal, state and local regulations. See the full Research Use Disclaimer.

Our products are intended strictly for laboratory research, and we are required to ensure only qualified legal adults engage with the catalog. You must be at least 21, or the legal age of majority in your jurisdiction — whichever is greater. We may also request a government-issued ID or institutional affiliation before processing an order. Details in the Age Verification Notice.

Orders placed before 12 PM EST are dispatched the same business day; anything later ships within one business day, excluding weekends and holidays. Everything travels in a plain, unmarked outer box with no branding or contents listing on the exterior, fully tracked via UPS. Insulated liners and cold packs are added where the compound requires them. Orders over $150 may require a signature.

We ship within the United States to all 50 states. International shipping may be offered on a case-by-case basis — buyers are responsible for verifying whether the products are permitted in their country and assume all risk for customs clearance or seizure. Research institutions outside the US should contact us with institutional details first.

Store sealed lyophilized vials at −20°C, protected from light and moisture. Short-term storage up to 30 days is acceptable at 2–8°C in original packaging. Allow vials to reach room temperature before opening to prevent condensation.

Introduce bacteriostatic water down the inside wall of the vial rather than spraying directly onto the lyophilized cake, then swirl gently — do not shake or vortex. After reconstitution store at 2–8°C and use within 30 days, avoiding repeated freeze-thaw cycles. Follow your own laboratory’s dilution procedure for exact volumes.

Contact us within 24 hours of delivery with your order number, photos of the package and product, and a description of the issue. If a lot fails to match its published certificate or arrives compromised, we will replace it. Because these are research-use materials, all sales are otherwise final — see the Return Policy.

Only if it has not yet been processed or shipped. Once an order has been fulfilled it cannot be altered, cancelled or refunded. Email us immediately with your order number and full name.

Yes. Bundle discounts run automatically at 5% for two units, 10% for three or more, 15% for five or more and 20% for ten or more. For larger institutional volumes, contact us with your requirements.

Because we only publish a certificate once the independent lab has returned it for that specific lot. A pending entry means the material has not yet been released against a published COA — not that it was skipped. If the lot code on a vial you hold is not in the library, contact us before use.

No. We supply materials for laboratory research and we are not a pharmacy. We can provide specification sheets, storage and handling references and lot documentation. We do not advise on use in humans or animals, and we will decline if asked.
