Coming Soon Important safety information

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

Where does my testosterone 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.

Do I need bloodwork before I start?

Yes. Testosterone is only prescribed after lab work confirms your levels are low and a licensed provider has reviewed your full medical history. We will tell you exactly which labs are needed and how to get them done. Nothing is prescribed before those results are in.

When will testosterone be available?

Not yet. Hormone care needs lab review and ongoing monitoring, and we are putting that in place before we open it up. Compounded GLP-1 and GIP-1 treatment is available today.

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 free 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.

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.

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 testosterone therapy?

Testosterone replacement therapy brings testosterone back into a normal range in men whose levels are clinically low, confirmed by bloodwork. It is prescribed and dosed by a licensed provider, and it needs ongoing lab monitoring for as long as you are on it.

Why an injection rather than a capsule?

Oral testosterone is broken down substantially by the liver before it reaches your bloodstream. Injection avoids that, which is why it is the most established route. Your provider sets the amount and the schedule based on your labs, your symptoms 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 testosterone?

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. Pause or cancel from your account at any time, up to 72 hours before your next scheduled processing date. Cancelling stops future orders. It does not reverse an order that has already been prescribed, dispensed or shipped.
