Shipping Policy
Where we ship
We ship within the United States only. We do not currently ship internationally, and we cannot accept orders for delivery outside the US.
Processing time
Orders are prepared within one to two business days. Orders placed at a weekend or on a public holiday are prepared on the next business day.
Carriers and rates
We ship via USPS and UPS. Rates are quoted live at checkout from the carriers themselves for your address and the weight of your order, so you see the actual services available rather than a fixed table. Standard delivery is typically three to five business days; faster services appear at checkout where the carriers offer them.
If a carrier's rating service is unavailable when you check out, a flat rate is offered instead so the order can still be completed. Delivery estimates come from the carriers and are estimates, not guarantees.
Where an order qualifies for free shipping, the cart shows it before you reach checkout.
Temperature-sensitive material
Lyophilised peptides tolerate ambient transit well — typically up to about two weeks at room temperature without measurable degradation — which is why standard shipping is suitable for most of the catalogue.
Orders are packed in insulated mailers with thermal protection appropriate to the destination and season. Sensitive material, including acylated GLP-1 analogues and longer sequences, ships with phase-change packs. Packaging is designed to moderate temperature swings; it does not hold a guaranteed temperature range in transit, and we cannot control conditions once a parcel is with the carrier.
Address accuracy
You are responsible for the address you enter. An order delivered to an address you supplied incorrectly is not eligible for a free replacement or refund, and a reshipment will require payment of shipping again. Check the address at checkout — our address verification flags some problems but cannot catch a valid address that is simply not yours.
P.O. boxes
USPS delivers to P.O. boxes; UPS does not. Entering a P.O. box therefore limits which services are available at checkout, and an order placed with a UPS service to a P.O. box may be delayed or cancelled.
Tracking
Every order ships with tracking. We email the tracking number when the order leaves us, and it is also shown on the order in your account or through order lookup if you checked out as a guest.
Delivery problems
If tracking shows a parcel as delivered and you do not have it, check with neighbours, building management, and the usual delivery spots, and allow 24 to 48 hours — carrier scans are sometimes early. If it still has not arrived, contact us.
Damage in transit and parcels that never arrive are handled under the Refund and Return Policy: contact support within 30 days of delivery with your order number and, for damage, a photograph.
Changes
We may update this policy. The version published here when your order is placed is the one that governs it.
