Suitability and Eligibility Criteria
Before we can fulfill your NadGo order, you have to certify the following eligibility criteria:
- I do not have a known allergy to NAD+
- I have not been diagnosed with cancer within the past three years.
- I do not have any severe respiratory issues.
- I confirm that the self-injection pen is intended for my personal use only.
- I am not currently pregnant.
Nicotinamide adenine dinucleotide (NAD+) is a coenzyme present in all living cells, essential for life and health. It serves as a critical helper molecule for enzymes, enabling key chemical reactions that drive cellular metabolism, energy production, and DNA repair.
Unlike oral NAD+ precursors, subcutaneous administration bypasses first-pass hepatic metabolism, delivering higher and more consistent plasma NAD+ levels. It also avoids the time, cost, and clinical burden of intravenous NAD+ infusions, making it ideal for regular use.
For a NAD+ self-injection pen, the best injection sites are areas with a layer of fatty tissue just under the skin — this helps with absorption and comfort. It is recommended to use areas such as the belly, buttocks or thigh.
Tips for best results:
- Rotate injection sites to avoid irritation.
- Always clean the area with an alcohol swab first.
- Avoid areas that are bruised, red, swollen, or hardened.
There are 20 doses in the vial. It is recommended to administer one dose daily for the first three days, followed by one dose every other day. Under this regimen, a single pen provides sufficient doses for slightly more than five weeks.
Do not share your device with others. Sharing can lead to risk of infection, incorrect dosing or safety issues.
Store the pen in the refrigerator (2–8°C). Keep away from direct light. Do not freeze. If left at room temperature for more than 4 hours, return to the fridge and use within 24 hours or discard.
You should dispose of your NAD+ pen’s needles and empty vials safely in the provided sharps bin.
Yes, you can. Transport cartridges in a cool pack or insulated bag. Avoid exposure to temperatures above 25°C for prolonged periods. Carry your pen and supplies as hand luggage, not in checked baggage.
