Important safety information

Compounded drug products are not approved or evaluated for safety, effectiveness, or quality by the FDA. Prescription required.

Where does my NAD+ come from?

A state licensed US compounding pharmacy prepares it for you, and every batch is third party tested for purity and potency. Compounded medications are not approved or evaluated by the FDA for safety, effectiveness or quality. Compounding pharmacies are licensed and inspected by state Boards of Pharmacy and are highly regulated. A prescription is required.

Does the price go up as my dose goes up?

No. You pay the same whether you are on your starting dose or your highest one. Plans start at $69 a month on the 12 month plan, which works out at about $2 a day. No hidden fees, no monthly membership, and free overnight shipping on every order.

What side effects should I expect?

Usually nausea, and usually early. Side effects most often show up in the first weeks after a dose increase and settle within a week or two. If they do not, message your care team and they will slow the climb rather than stop it. Always read the information supplied with your medication, and contact your provider about anything that concerns you.

How it works

From first question to front door.

What you get with Science & Co

A treatment plan with dose adjustments when clinically appropriate, a quick online assessment reviewed by a licensed provider, secure messaging and scheduled check ins with your care team, and medication shipped cold packed to your door. Every plan includes supplies, shipping and ongoing clinical monitoring.

How to take it

A once weekly injection you give yourself, on the same day each week unless your provider tells you otherwise. You start low and step up on a set schedule, which gives your body time to adjust and keeps side effects manageable.

Potential side effects

The most common side effects are nausea, constipation and diarrhoea, and they usually settle as your body adjusts to each step up in dose. Your provider reviews how you are doing at every check in and can slow the schedule down if you need it.

How does Science & Co ensure quality and safety?

We work only with state licensed US compounding pharmacies. Every batch is third party tested for purity and potency, and you can request a Certificate of Analysis for your prescription at any time.

The food noise went quiet by about week three. I stopped negotiating with myself at dinner and everything after got easier.

The weight came off steadily instead of all at once, and my provider adjusted my dose whenever the loss started to stall.

I am two sizes down and the clothes I had given up on fit again. None of it turned my week into a second full time job.

Marcus T.

I spent years stuck at the same number on the scale. It started moving in the first month and it has not gone back up yet.

Angela R.

I have kept the weight off for eight months now. It stopped feeling like willpower and started feeling like a normal day.

INSIDE THE PROTOCOL

Start low. Adjust often.

Semaglutide is not a fixed dose you take and hope for. You start low, step up on a schedule your provider sets, and hold wherever your body is responding well. That is the part most people never get, and it is the part that makes it liveable.

The weight kept coming off even when my provider held the dose steady. Nobody pushed me to the next number just to chase a faster result.

FAQ

Common
questions

What is NAD+?

Three steps. NAD+ is nicotinamide adenine dinucleotide, a coenzyme present in every cell and involved in how cells produce energy and carry out repair. Levels fall as you get older. It is prescribed and dosed by a licensed provider, and it is not approved by the FDA to treat, cure or prevent any disease.

Why an injection rather than a capsule?

One pathway versus two. Injection bypasses digestion. Oral NAD+ is broken down substantially before it reaches your cells, which is why it is commonly given subcutaneously instead. Your provider sets the amount and the schedule based on your history and how you respond.

Do I need insurance to get started?

No. Science & Co is a cash pay service with transparent pricing, so there are no claims to file, no prior authorizations, and no surprise bills. Your plan covers the provider evaluation, your medication, and ongoing support.

Who prescribes my NAD+?

A licensed provider. Every prescription is written by a provider licensed in your state, after a real clinical review of the intake you complete. They stay available for follow up as your plan continues, and nothing is dispensed without their approval.

How long until I notice a change?

Appetite usually quietens first. Most people notice appetite changes within the first few weeks, usually before the scale moves. Because you start at a low dose and step up gradually, the early weeks are about tolerance rather than results. Your provider tracks how you are responding at each check in and adjusts from there.

Can I pause or cancel at any time?

Yes. There is no lock in and no cancellation fee. You can pause your plan if life gets in the way and pick it back up later, or cancel outright from your account.
