Common Questions

Everything researchers ask before ordering.

How fast does this ship?

Orders placed before 2 PM EST ship the same business day from our Tacoma, WA facility. Standard delivery is 2–4 business days; expedited options are available at checkout. You will receive a tracking number as soon as the label is created.

What is included with each vial?

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

How is purity verified?

Every batch is tested by an independent lab using HPLC for purity and LC-MS for identity. The COA is stamped with the batch number, test date, and lab name, and uploaded to this page before any vial from that lot ships.

How should this be stored?

Lyophilized peptides are stable at room temperature for short-term shipping but should be kept at –20°C for long-term storage. Reconstituted product should be refrigerated at 2–8°C and used within the window noted on the COA.

What payment methods do you accept?

All major credit and debit cards through our secure checkout. We do not store payment information; transactions are processed by a PCI-compliant gateway.

What is your return policy?

If your order arrives damaged or does not match its COA, contact us within 30 days for a full refund or replacement. Because of the research-use nature of these products, we cannot accept returns of opened vials outside of those circumstances.

Do you ship internationally?

Currently US-only. International shipping is on the roadmap but not yet enabled — sign up for our list and you will be notified when we open more regions.

Are these products for human use?

No. All products on this site are sold for laboratory research use only. They are not intended to diagnose, treat, cure, or prevent any disease, and are not for human or veterinary consumption. By purchasing, you confirm you are a qualified researcher.
