Frequently Asked Questions
Everything you need to know about our products, testing protocols, and ordering process.
No. All products sold by PrimeNexa Labz are strictly intended for in-vitro research and laboratory use only. They are not intended for human or animal consumption, and we do not provide guidance on dosing, administration, or therapeutic use. By purchasing from us, you acknowledge and agree to these terms.
Every batch undergoes rigorous third-party testing through independent, ISO-accredited laboratories. We use High-Performance Liquid Chromatography (HPLC) and Mass Spectrometry (MS) to verify identity, purity, and composition. Certificates of Analysis (COAs) are available for every product and can be downloaded directly from the product page.
Orders placed before 2:00 PM EST on business days ship the same day via FedEx 2Day, with delivery in 2 business days. Shipping is a flat $15, and free for any order of $250 or more after discounts. We ship within the United States only, and some research compounds cannot be shipped to every state.
Once your order ships, you will receive an email confirmation containing your tracking number and a direct link to the carrier’s tracking page. You can also view the status of all current and past orders by logging into your account on our website. If your tracking information has not updated within 48 hours of shipment, please reach out to our support team.
Due to the nature of our products, all sales are final and we do not accept returns. We do refund or replace orders with a defective product or a shipping error — wrong items, missing items, or a package that arrives damaged. Contact us right away if that happens, and keep the packaging until it is resolved.
