Sealed, desiccated, tracked.

1. Where we ship

We ship to street addresses within the United States only. We do not ship internationally, and we do not accept orders for delivery to freight forwarders, mail-forwarding services, or parcel-consolidation addresses.

We may decline delivery to any jurisdiction where the sale or possession of a product is restricted, and may cancel and refund an order for that reason after it has been placed.

Delivery address requirements. We ship to commercial, institutional and residential addresses. We do not ship to P.O. boxes.

2. Processing and dispatch

Orders are processed on business days, Monday through Friday, excluding U.S. federal holidays.

• Orders confirmed and paid before 2:00 p.m. ET on a business day are dispatched the same business day.
• Orders confirmed after that time, or on a weekend or holiday, are dispatched the next business day.
• Orders may be held pending payment verification, fraud screening, or confirmation of the purchaser representations in Section 2 of our Terms of Sale. We will contact you if a hold applies.

Dispatch time is not delivery time. Transit time depends on the carrier and service selected.

3. How your order is packed and shipped

Our products ship dry, at ambient temperature. Refrigerated transit is not used and is not required.

Each product is supplied as a sealed lyophilized solid, closed under inert headspace with a crimp seal and flip-off cap. Vials are seated in a die-cut foam insert inside a rigid outer box with desiccant and a tamper-evident closure. Shipments are unmarked as to contents beyond what carrier regulations require.

Refrigerate on arrival. The vial label reads STORE COLD 2–8 °C. Move the vials into a refrigerator at 2–8 °C when you unpack the box, or into a −20 °C freezer if the material is going into long-term storage. Keep them sealed and dry until you are ready to use them.

Storage instructions after receipt also appear on the vial label, on the product page, and on the packing insert. They are storage conditions, not transit conditions: lyophilized material is stable dry and at ambient temperature for the length of a tracked shipment, which is why refrigerated transit is neither used nor required. Refrigeration is what the material needs once it is on your shelf, not on the way there.

4. Shipping methods, rates, and tracking

Carriers used: USPS and UPS. Adult signature is not required on delivery.

A tracking number is emailed when your label is generated. Tracking may take up to 24 hours to show carrier movement. Once a shipment is tendered to the carrier, transit is under the carrier's control.

5. Address accuracy, refused and undeliverable shipments

You are responsible for the accuracy of the delivery address you provide. We cannot reroute a package after dispatch.

If a shipment is returned to us as undeliverable, refused, or unclaimed, we will refund the product price less shipping charges and less a 15% restocking fee, and only if the outer packaging and vial seals are intact on return. Material returned with compromised seals cannot be restocked or refunded, for the integrity reasons stated in Section 8 of our Terms of Sale.

6. Damage, shortage, and loss claims

Inspect your shipment on arrival.

Damage or shortage. Report it within 7 calendar days of delivery to support@peakpulselabs.com with your order number, photographs of the outer box, the inner packaging, and the affected vials including the label and lot number, and a description of the issue. Retain all packaging until the claim is resolved. Approved claims are resolved by replacement of the affected material or refund of the amount paid for it, at our option.

Lost in transit. If tracking shows no movement for 7 consecutive business days, or shows delivery but you did not receive the package, notify us within 14 calendar days of the last tracking update. We will open a carrier investigation, which the carrier may take several weeks to complete. Where the carrier confirms loss, we will replace the shipment or refund it at our option.

Marked delivered but missing. Where tracking confirms delivery to the address you provided, we are not responsible for theft or misplacement after delivery, but we will assist with a carrier claim. Select a signature-required service at checkout if this is a concern.

7. Returns

Because we cannot verify the storage conditions or chain of custody of material that has left our control, all sales are final. We do not accept returns or exchanges of opened, unsealed, decanted, relabeled, or previously shipped material. Your remedies for damaged, short, lost, or nonconforming shipments are those in Section 6 above and Section 9 of our Terms of Sale.

We do not accept returns for change of mind, ordering the wrong compound or fill mass, or delayed transit within the carrier's published service window.

8. Order changes and cancellations

You may request a change or cancellation before dispatch by emailing support@peakpulselabs.com with your order number. Once a label is generated we cannot modify or cancel the order. Cancellations approved before dispatch are refunded in full to the original payment method; refunds typically post within 5–10 business days depending on your issuer.

9. Certificates of analysis

Every shipment includes a packing insert stating the lot number for each vial. The certificate of analysis for that lot is published at coa.html and is searchable by lot number. Certificates remain available after a lot sells out. If a lot number on your vial does not resolve to a published certificate, contact compliance@peakpulselabs.com before use.
