Frequently asked questions
Everything about ordering, certificates of analysis, payment, and shipping. Can't find it? Contact us.
What does "research use only" mean?
All products are laboratory reference standards supplied solely for in-vitro research. They are not for human or veterinary use, and they are not drugs, foods, dietary supplements, cosmetics, or medical devices. They have not been evaluated or approved by the FDA.
Who is allowed to purchase?
Vexum Labs sells to businesses only. To order, create a business account with your company's legal name, address and your role, and sign the business certification. We review every account and email you once it is approved; until then it cannot place an order. Buyers must also be at least 21 and confirm research use, which is recorded with each order.
Why do I need a business account?
Our products are research materials sold to businesses, never to individual consumers. Checking each business before it can order is how we keep it that way. We may ask for documents that confirm the business, such as its formation documents or IRS EIN letter.
Is a Certificate of Analysis available?
Yes. Every lot is matched to a third-party Certificate of Analysis covering identity and purity. The COA Library is searchable by product name or lot number, and every certificate can be downloaded before or after purchase.
Can you advise on how to prepare or use a product?
No. We do not provide preparation, measurement, handling, or application instructions, and we cannot answer questions about use in or on humans or animals. For specifications, see the product page and its Certificate of Analysis; for handling, consult the applicable safety data sheet and your institution's procedures.
How can I pay?
At checkout you choose a payment method (PayPal, Venmo, Cash App, Zelle, Apple Cash) and send the order total directly to us. After you place the order, email a screenshot of your payment to support@vexumlabs.com as proof. Your order is reserved and ships once we confirm payment. No card is charged on the site.
How is my order shipped?
Shipping options, timing, and regions are described in our Shipping Policy. Orders ship in plain, unbranded packaging with carrier tracking, which becomes available from your account and the Track page once a label is created.
What is your return policy?
Unopened, untampered items still vacuum-sealed in their original packaging can be returned within 30 days of delivery. Opened items cannot be returned. Damaged, incorrect or lost orders are replaced or refunded in full. Our Refund & Returns Policy has the full conditions and how to start a return.
How do I track an order?
Sign in to your account to see order history and status, or use the Track page with your order number and the email on the order.
