Common Questions

What researchers ask before ordering.

How fast does this ship?

Orders placed before 6 PM ET ship the same business day from our U.S. facility. Standard delivery runs 2–4 business days; faster options are available at checkout. You'll get a tracking number the moment the label prints.

What's included with each vial?

Every order ships with the lyophilized vial, a tamper-evident seal, and a packing slip that lists the batch ID. The matching certificate of analysis lives on this page and in your account downloads after purchase.

How is purity verified?

Every batch is tested by an independent U.S. lab — HPLC for purity, mass spec for identity. The COA is stamped with the batch number, test date, and lab name, and posted here before any vial from that lot ships.

How should this be stored?

Lyophilized peptides are stable at room temperature for short-term transit but should be kept at −20 °C for long-term storage. Once reconstituted, refrigerate at 2–8 °C and use within the window noted on the COA.

What payment methods do you accept?

All major credit and debit cards through our secure checkout, plus crypto. We never store card details — every transaction runs through a PCI-compliant gateway.

What's your return policy?

If your order arrives damaged, contact us within 30 days for a full refund or replacement. Given the research-use nature of these compounds, we can't accept returns on opened vials outside those cases.

Do you ship internationally?

We ship across the contiguous U.S., plus Canada and the U.K. More international regions are on the roadmap — join our list and we'll let you know the moment new ones open.

Are these products for human use?

No. Every Novalabs compound is strictly for laboratory and research use only — not for human or animal consumption.
