Frequently asked questions

Answers to common queries about our website, products and services

What is your refund/cancellation policy?

At Cenara, you are free to cancel, postpone, or pause your subscription at any time (and for any reason) prior to your next shipment. If at all possible, we kindly ask for a minimum of 48 hours notice before your next order is set to process. Cenara cannot guarantee refunds for any cancellation requests received after the pharmacy has processed your order. Furthermore, Cenara does not accept returns nor can we offer any refunds for any prescription product once it has left our pharmacy partner. If you experience any issues with your shipment, or are dissatisfied with your product, please contact our team within 30 days following your order fulfillment. We will be more than happy to help make things right.

Who are the doctors?

We use an accredited network of Board-certified physicians. You can rest assured knowing that your intake form will be viewed by an actual doctor and your medication will be prescribed by someone with the right experience.

Where are medications shipped from?

Your medication will ship from our certified pharmacy partners which have locations all across the continental US in order to guarantee fast, secure shipping.

When is my medication shipped?

Tracking Information: You will receive tracking information once your order has been shipped. This will allow you to monitor the delivery status.

What is NAD+ and why does it matter?

Nicotinamide adenine dinucleotide (NAD+) is the co-enzyme that turns food into cellular energy and drives DNA repair. Research shows levels can decline up to 50 % by mid-life, contributing to sluggish metabolism and brain fog. Restoring NAD+ helps many people feel sharper, recover faster, and support healthy aging.

Are NAD+ injections safe?

Safety is our first priority. Every prescription is reviewed by a U.S.-licensed clinician, filled with USP-grade NAD+ at an FDA-registered 503B pharmacy, and third-party tested for potency and sterility before it ships.

Does it hurt?

Feedback averages 2 / 10 or less on a comfort scale. We supply ultra-thin insulin syringes plus a short video walkthrough so most members self-inject in under a minute—no medical background needed.

Do I need to see a doctor in person?

Absolutely not. Complete the online questionnaire, hop on a quick telehealth call if your provider needs clarification, and we ship your chilled medication free to your door—all without a clinic visit. Easy, right?

Who shouldn't get NAD+ injections?

People who are pregnant, breastfeeding or have uncontrolled heart disease should check with their primary physician first. Your telehealth provider screens for contraindications and will recommend alternatives if NAD+ isn’t the right fit.

Which states do you ship to?

At the moment, we serve the entire US except for the following states: Alaska, Mississippi, New Hampshire, New Mexico.
