01Order processing
Orders with payment confirmed before 2 PM PT on a business day (Monday–Friday, excluding U.S. federal holidays) are dispatched the same day. Orders confirmed after the cutoff, or on a weekend or holiday, are dispatched the next business day.
During product launches, restocks, or periods of high volume, processing may take slightly longer. If an item in your order is unexpectedly unavailable, we will contact you before shipping a partial order.
02Shipping rates
- Flat-rate shipping: $12.00 per order.
- Free shipping on orders of $250.00 or more (after discounts are applied).
The shipping charge for your order is always shown in your cart and at checkout before you pay. Any applicable sales tax is calculated at checkout.
03Carriers & delivery estimates
We ship with established carriers such as USPS, UPS, and FedEx, and choose the service that best balances speed and reliability for your destination.
- Contiguous United States: typically 2–4 business days after dispatch.
- Alaska, Hawaii, U.S. territories, and APO/FPO addresses: typically 5–10 business days after dispatch, where we are able to ship.
Delivery times are estimates provided by carriers and are not guaranteed. Weather, carrier volume, and other events outside our control can cause delays.
04Where we ship
We currently ship to the United States. Checkout will only accept shipping addresses in these locations. We may decline or cancel orders to destinations where a product is restricted, and certain products may not be available everywhere.
We do not currently ship internationally. If that changes, this policy will be updated with the additional destinations and the import responsibilities that apply.
Regardless of destination, it is the buyer’s responsibility to confirm that products may lawfully be purchased and received at the shipping address, including under applicable state and local laws.
05Discreet, protective packaging
Orders ship in plain, unbranded outer packaging with no product names on the exterior. Vials are sealed, labeled with product and lot information, and packed with protective materials to prevent breakage in transit. The shipping label shows a neutral return name and address.
06Tracking & notifications
When your order ships, we email you the carrier name and a tracking number. You can also follow your order’s progress from your account, or as a guest on our order tracking page using your order number and email address. Please add our sending address to your contacts so order emails don’t land in spam.
07Address accuracy
Please double-check your shipping address at checkout. We ship to the address exactly as entered and cannot be responsible for delays or losses caused by incomplete or incorrect addresses. If you notice a mistake, email hello@darksidelabs.org immediately with your order number. We can update the address only before the order has been dispatched.
08Temperature & storage on arrival
Our peptides are supplied in lyophilized (freeze-dried) form, which is stable at ambient temperatures for the normal duration of transit, so they do not require cold-chain shipping. Bacteriostatic water and other liquids are sealed and packed to prevent leakage.
On arrival, inspect your package and transfer products to storage under the conditions stated on each product page and label as soon as possible. Proper storage, handling, and laboratory safety after delivery are the buyer’s responsibility.
09Lost, damaged, or incorrect shipments
If a package is lost in transit, arrives damaged, or contains the wrong items, contact hello@darksidelabs.org within 7 days of delivery. Claims, replacements, and refunds are handled under our Refund & Returns Policy.
