Shipping & Returns

Processing & Shipping Times

Orders placed before 4:00 PM EST on a business day ship the same day. Orders placed after that cutoff, or on a weekend, go out the next business day. Once handed to USPS, standard shipping typically takes 2–5 business days depending on your location.

Shipping Cost & Coverage

Standard USPS shipping is free on every order, with no minimum — we don't run promotional thresholds. We currently ship to addresses within the United States only; international shipping isn't available yet.

Tracking Your Order

You'll receive a tracking number by email as soon as your order ships. You can also look up any order anytime — with or without an account — on our Track Your Order page using your order number and checkout email.

Damaged, Missing, or Incorrect Items

Mistakes are rare but they happen. If your order arrives damaged, incomplete, or incorrect, contact us within 7 calendar days of delivery with:

• Your order number
• Photos of the item(s) and shipping label as received
• Unboxing video, if you have one — it speeds up verification

Once we verify the issue, we'll ship a free replacement. We do not offer cash refunds for shipping errors — only replacement of the affected item(s).

Returns & Refunds

Because our products are sold for laboratory research use and payments are processed manually with no card-network involved, all sales are final once an order ships. We're unable to accept returns or issue refunds for:

• Change of mind or ordering the wrong size/compound
• Packages marked delivered by the carrier — we're not able to cover loss or theft after delivery confirmation
• Products that have been opened or reconstituted

This doesn't affect the replacement coverage above for genuine damage, shipping errors, or defects on our end.

Order Changes & Cancellations

You can request a change or cancellation any time before your order ships — email support with your order number and we'll do our best to accommodate it. Once a package has been handed to USPS, it can no longer be recalled or modified.

Undeliverable & Refused Packages

If a package is returned to us as undeliverable due to an incorrect or incomplete address, we'll reach out to confirm the correct details before reshipping. A reshipment fee may apply if the address error was on the customer's side.
