Straight answers about ordering, testing and shipping.

Payment is by Zelle. Place your order and choose Zelle at checkout. Your order is reserved and you see the Zelle recipient and the exact total straight away. Send that amount from your bank app with your order number in the memo, then upload a screenshot of the completed transfer. A real person confirms it, usually the same business day, and dispatch follows. Orders without payment after 48 hours are released and cancelled; nothing is charged.

Zelle moves money directly between bank accounts with no card processor in between. You never enter card details on this site and we never see your bank login. To keep it safe on your side: send only to the recipient shown on your order page, send the exact total, and keep the receipt until you receive the confirmation email.

Yes. Guest checkout is open. An account adds the 25% welcome code on your first order, saved addresses and an order history with dispatch estimates.

Email [email protected] with your order number and the Zelle receipt. A person will match the transfer to your order and tell you if anything is still owed or due back.

In-stock items ship the same business day when payment is confirmed before 1:00 PM Central, Monday to Friday. Some sizes are made to order and ship in 7–10 days. The product page shows which applies to the size you select, and your cart and confirmation email show the estimated dispatch date. Every order, in stock or made to order, ships from Illinois.

No. Cenvia Labs ships within the United States only, from Illinois. Checkout does not accept a non-US address.

Shipping options and rates are shown at checkout. Standard shipping is free over $200.00.

You receive an email with tracking when your order ships. You can also enter your order number and email on the Track Order page, or open the order under My Account if you have one.

Every product is third-party tested by an independent laboratory. We work with independent laboratories including Janoshik, Freedom Diagnostics and Kovera Labs. The laboratory runs the analysis and issues the certificate of analysis, and each certificate states the lot that was tested. Cenvia does not test its own material.

A certificate is on file for every product. When a certificate is published to a product page it appears as a result card under the buy box for the size you select, with the lab and its task number, the lot that was tested, the analysis date, the labeled and measured amounts and the purity where the lab reports one. “View full report” opens the lab’s report as we received it, and “Verify” opens the lab’s own page for that test in a new tab, with the verification key printed on the report shown under the link. You can also look up a lot number on the Certificates of Analysis page. Certificates are available on request from [email protected].

The lab is named on the certificate. A product page names a laboratory only when a certificate from that laboratory is on record for that product, so what you see on the card is what the certificate says.

Every product is a lyophilized powder in a sealed vial, labeled with the compound name, the size and the lot number. Each product page lists the CAS number, molecular formula, molecular weight, sequence and appearance where verified, and the components and amounts for blends.

Store the sealed vial at −20 °C, protected from light and moisture, and keep it sealed until use. The storage conditions are repeated on every product page.

No. Every product is sold strictly for laboratory research, so we do not publish or discuss dosing, reconstitution, administration or use. Questions of that kind cannot be answered by support.

Create an account and the code WELCOME25 takes 25% off your first order. It is applied automatically at checkout while you are logged in, works once per account and is for first orders only. It cannot be used as a guest, and it is checked against both your account and your billing email.

Every size is priced per vial. One vial is list price, and buying 3, 5 or 10 vials lowers the per-vial price, and each product page shows the exact price for every tier. The tiers are presets, so you can enter any quantity and the per-vial price is the best tier at or below it. When the next tier would cost less than, or about the same as, the quantity in your cart, the product page and the cart offer it in one click. The cart shows the per-vial price and how much you saved.

Unopened vials can be returned. Email [email protected] with your order number before sending anything back, and we will confirm the address and the refund method. Opened vials cannot be accepted, because the material cannot be verified once the seal is broken. The full policy is on the Returns page.

Email us within 7 days of delivery with your order number and a photo. Damaged or incorrect items are replaced at no cost, or refunded if you prefer.
