Shipping, returns & support
Everything you need to know about turnaround times, tracking your order, our returns policy, and reaching a human at Halcyon.
Order processing
1–2 business days
Orders placed before 3pm EST on business days are typically prepared and handed to the carrier within one business day. Blends and custom-lot requests may add 24–48 hours.
Domestic transit
2–4 business days
USPS Ground Advantage and UPS Ground are our domestic methods, chosen by destination and parcel size. Shipping is calculated live at checkout, and orders over $125 before shipping ship free.
Domestic only
United States
We ship within the United States only, including Alaska, Hawaii, and U.S. territories. We do not accept or fulfill orders shipping outside the United States.

Returns
Straightforward, science-first policy
No returns on shipped product
Because storage and handling can't be verified once material leaves our facility, we do not accept returns on shipped vials, opened or unopened.
Damaged or lost in transit
Report visible damage or a missing shipment within 5 business days, with photos where relevant, and we'll replace or refund the affected items.
Wrong item received
If a shipment doesn't match your order, contact us within 5 business days and we'll correct it at no cost.
Cancellations
Before an order ships you can request cancellation from My orders; we review each request and you'll see the decision on the same page.
