Shipping Rates
Shipping rates are calculated at checkout based on the total weight of your order and your delivery destination. You will see all available options and their costs before completing your purchase. We do not mark up shipping rates.
Tracking
Once your order has shipped, you will receive an email containing your tracking number and a link to track your package directly with the carrier. Please allow up to 24 hours after receiving your tracking number for the carrier's system to update with scan information.
Cold Chain & Storage
Lyophilized (freeze-dried) peptides are stable at room temperature during transit and do not require refrigeration for shipping. For orders over $150 placed during summer months (June–September), we include cold packs as an added precaution to maintain product integrity in high ambient temperatures.
Upon receipt, we recommend storing lyophilized peptides in a cool, dry place away from direct light. Reconstituted peptides should be refrigerated and used promptly per your research protocol.
Return Policy
Due to the nature of research chemicals and to ensure product integrity, all sales are final. We do not accept returns or exchanges under any circumstances. Please review your order carefully before completing your purchase.
Damaged or Incorrect Orders
If your order arrives damaged or you receive an incorrect item, please contact us within 48 hours of delivery with photographic evidence of the issue. We will review your claim and, at our sole discretion, reship the correct item or issue store credit. Claims submitted after the 48-hour window may not be eligible for resolution.
Lost Packages
If your package has not arrived within 10 business days of the expected delivery date, please contact us through our website. We will open an investigation with the carrier on your behalf and work diligently to resolve the situation. Please note that packages marked as "delivered" by the carrier are not considered lost — if you believe your package was stolen, please file a report with your local authorities.
