Shipping Policy
Flat-rate tracked shipping within the United States, dispatched within 24 hours of payment clearing. Everything below is what we commit to, and what happens when a shipment does not go to plan.
Standard — $15.00
Tracked domestic delivery, flat rate regardless of order size or weight.
Free over $150.00
Applied automatically at checkout. No code required.
Orders are picked, packed and handed to the carrier within 24 hours of payment clearing. Payment clearing — not order placement — starts the clock, because an unpaid order is not yet an order.
- —Orders placed and paid on a business day before mid-afternoon generally leave the same day.
- —Orders paid overnight or at a weekend leave on the next business day.
- —We do not dispatch on federal holidays.
- —If an item turns out to be unavailable after payment, we contact you the same day with the choice of a substitution, a partial dispatch, or a full refund.
A tracking number is generated when the shipping label is created and is added to your account immediately — you do not have to ask for it. You can find it under your order at any time.
Transit time is set by the carrier and by distance, and we do not control it. We commit to the dispatch window above; we do not guarantee a delivery date, and we will not quote you one we cannot keep. Tracking may take up to 24 hours after dispatch to show its first scan, which is normal and not an indication of a problem.
Every order is packed discreetly. The outer packaging carries no product names, no compound names, and no external indication of contents. The return address is the business address below.
Vials are packed to survive normal carrier handling. Where a shipment is packed with a cold pack, that is to limit thermal excursion in transit — arrival at ambient temperature is not itself evidence of a problem, and material should be moved to its stated storage conditions on arrival.
We ship within the United States only, from our facility in Texas. Domestic shipping means no customs exposure and no international seizure risk. We do not currently ship internationally and cannot arrange forwarding.
We ship to residential and business addresses. We cannot ship to a address we cannot verify with the carrier.
Tracking has not updated in several days
Carrier scans occasionally lag, particularly over a weekend. Email us with your order number if there has been no movement for three business days and we will open a trace with the carrier.
Marked delivered, not received
Check with anyone else at the address and with immediate neighbours first, as carriers sometimes scan early or leave a parcel in a safe place. If it does not appear within 48 hours, contact us and we will file a claim. A parcel marked delivered by the carrier is not covered by our damage policy, but we will pursue the carrier on your behalf.
Arrived damaged
Photograph the vial and the outer packaging before discarding anything and contact us within 48 hours. See the returns policy for the full claims process.
Wrong address entered
Email us immediately. If the label has not been created we will correct it at no cost. Once a parcel is in transit we cannot redirect it, and losses arising from an incorrectly entered address are not covered.
Returned to sender
Undeliverable parcels come back to us. We will contact you to arrange a reship, which is charged at the standard rate, or a refund of the product value less original shipping.
