Returns & Refunds

We stand behind the quality of every batch. Here’s how returns, replacements, and refunds work.

Protection on every order

Because our products are research materials — many of them lyophilized, temperature-sensitive compounds — we cannot resell items once they have left our custody. Instead, every order is protected: if it arrives damaged, is incorrect, or does not meet the specifications on its Certificate of Analysis, we will make it right with a replacement or refund.

How returns work

1

Document the issue

Photograph the outer packaging, packing slip, and affected products as soon as your order arrives — clear photos are required for every claim.

2

Email our team

Contact support@kestraclub.com within 7 days of delivery (14 days for wrong or defective items) with your order number and photos.

3

Replacement or refund

Once we’ve reviewed the evidence, we ship a replacement or, if you prefer, issue a refund for the affected items.

Eligible for return

  • Products damaged in transit, reported within 7 days with photos
  • Wrong product or incorrect variant received
  • Items that do not match the specifications on their Certificate of Analysis (within 14 days)
  • Unopened, still-sealed items with prior return authorization

Not eligible for return

  • Opened, used, or unsealed products
  • Temperature-sensitive compounds that have left our controlled storage
  • Items marked final sale, clearance, or promotional bundles
  • Gift cards and digital items
  • Any product returned without prior authorization

Important notes

  • All products are supplied strictly for laboratory and research use only — not for human or veterinary use.
  • Keep the original packaging until your claim is resolved; it may be needed for the carrier’s shipment-protection review.
  • Where an eligible, unopened item is returned for reasons other than our error, a restocking fee of up to 15% may apply and outbound shipping is non-refundable. We’ll always tell you whether a fee applies before you send anything back.
  • If you’re unsure whether your situation qualifies, reach out anyway — we’d rather hear from you.
