Coming Soon Important safety information

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

What is KPV used for?

Inflammation, and gut inflammation in particular. Much of the lab work is on the intestinal lining, which is why it shows up in gut protocols rather than injury ones.

KPV comes from a tanning hormone. Will it change my skin?

No. Melanotan I and II are built to hit the receptors that drive pigmentation. KPV doesn't bind them. Using the tail fragment instead of the whole hormone is how that effect gets left behind.

Where does my KPV 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.

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.

Rachel M.

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

Danielle P.

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

Why is KPV used alongside BPC-157?

They come at the gut from different directions. BPC-157 is studied for repair of the lining, KPV for the inflammation around it. Your provider decides whether pairing them makes sense for you.

Does KPV have to be injected?

Not always. At three amino acids it's small enough that oral and topical routes are possible, which is unusual for a peptide. Your provider chooses the route.

Can I take KPV with a GLP-1?

It's a fair question, since stomach upset is the most common complaint on a GLP-1. Your provider makes the call, and they can see everything you're already taking.

Why is KPV a fragment instead of the whole hormone?

The whole hormone does several things at once, including pigmentation and appetite. Isolating the tail keeps the part researchers care about and leaves the rest behind.

Is KPV a hormone or a steroid?

Neither. It's three amino acids taken from a hormone, which isn't the same as being one, and it doesn't act on the receptors the parent hormone does.

What does the KPV research cover?

Mostly lab and animal work on inflammation, much of it in the gut and some on skin. That's why you won't see outcome claims here, and why your provider guides how you use it.
