FAQ
Questions,
answered.
Quality, methodology, shipping, and the small print. If you can’t find what you need below, the team replies inside one business day.
Use & eligibility
Are NextGen compounds approved for human use?+
No. Every product on this site is supplied strictly for laboratory and research use. We make no medical claims and the material is not for diagnostic, therapeutic, or recreational use.
Who is allowed to purchase?+
Buyers represent that they are 21+ and purchasing on behalf of a legitimate research operation, that they understand the regulatory framework that applies to their jurisdiction, and that they will handle, store, and dispose of all material accordingly.
Will I be asked to verify my identity?+
A lightweight age affirmation appears at checkout. For institutional accounts we additionally verify the affiliation and ship-to address before fulfillment.
Quality & methodology
How do you verify identity and purity?+
Every lot is HPLC-purified to ≥99% on the principal peak and identity-confirmed by mass spectrometry against the theoretical molecular mass. The result is recorded on the lot's certificate of analysis.
What does the CoA include?+
Compound name, lot reference, test date, the HPLC purity result, and the issuing lab. BioRegen certificates also record mass-spectrometry identity confirmation; Janoshik certificates also record measured net content. Certificates do not include endotoxin, sterility, or pyrogen results.
Is the material endotoxin tested?+
No. Our certificates cover identity and HPLC purity — they are not sterility or endotoxin releases. No LAL assay is run on these lots, and the endotoxin field on every certificate reads “Not tested”. If your protocol requires an endotoxin limit, assay the material on receipt or contact us before ordering.
How is material stored before shipment?+
Lyophilized, vacuum-sealed, and held at −20°C until dispatch.
Shipping & handling
How long does shipping take?+
Standard shipping is 5–7 business days within the United States via FedEx or UPS, with full tracking.
Do you ship internationally?+
Not during this rollout — we currently ship within the United States only.
How is cold-chain integrity maintained?+
Vials ship vacuum-sealed inside an insulated container with phase-change cold packs to hold temperature in transit.
What if a shipment arrives compromised?+
Photograph the seal and packaging on receipt and email info@nextgenbio.io within 48 hours. We re-ship a damaged or cold-chain-compromised parcel at no charge once confirmed.
Orders & accounts
Do I need an account to order?+
Not for this rollout. NextGen ships as guest checkout — order ID + email is the lookup pair you'll need to track or reference an order later.
Can I get a quote for a standing order?+
Yes — email info@nextgenbio.io with the compounds and volumes you need and we'll quote standing-order pricing and lot-locked supply.
What's the return policy?+
All sales are final — research-use materials cannot be returned once shipped, because lot integrity cannot be verified after they leave our facility. Wrong items, parcels damaged in transit, cold-chain excursions on arrival, and defective lots are covered separately. See the full Return Policy.
Sourcing & research
Are reference standards available?+
For compounds in the catalog we offer reference-grade material with a certificate of analysis suitable for analytical method development and comparison work.
What documentation ships with an order?+
Certificates in our library record the HPLC purity result, the issuing lab, and the test date — plus mass-spec identity (BioRegen) or measured net content (Janoshik). Reference the lot number on the vial against the certificate on receipt.
