The short answer

As often as your provider prescribes. No study has compared NAD+ injection schedules, so frequency is an individual decision based on your health, your dose and how you feel between shots.

There's no evidence-based standard schedule for NAD+ injections.
Frequency and dose work together; changing one affects the other.
Side effects and how you feel guide adjustments.
Keep a simple log to share at check-ins.

Why schedules differ

Approved medicines get their schedules from trials that test different intervals. NAD+ injections haven't had those trials, so schedules come from your provider's judgment, the product's strength and your response.

What your provider weighs

Your dose per injection and the vial's strength
How you tolerate each shot
Your routine, so the plan is one you can keep
Whether you're starting out or continuing

Injection days are set by your provider and logged by you.

Your calendar

A plan set for you

Your provider picks the days; you pick a time that fits your life. Consistency matters more than any particular weekday.

Tips for staying on schedule

Pick the same days and time each week, rotate sites in order (left belly, right belly, left thigh, right thigh) and write down each dose, site and any side effects. That log makes check-ins more useful.

Questions

Questions people also ask

Is daily better than weekly?

No one knows. Schedules haven't been compared in studies, so your provider tailors yours.

Can I take a break?

Yes, talk to your provider. No withdrawal effect has been described for NAD+, but they can plan how to stop or restart.

Do I inject at a certain time of day?

Pick a consistent time. If evening doses keep you up, ask your provider about mornings.

What if I miss a scheduled shot?

Follow your provider's instructions. Don't double up to make up for a missed dose unless they tell you to.

Can I change my schedule myself?

Talk to your provider first. Dose and frequency are set together, so changing one affects the other.

Does the schedule change over time?

It can. Your provider may adjust it at check-ins based on how you tolerate NAD+ and what you notice.
