What is CagriSema?
Plain language first. The technical label stays, but it never stands alone.Overview
CagriSema is a fixed combination of cagrilintide (an amylin copy) and semaglutide (a GLP-1 copy) in one weekly shot. In plain terms: it hits two separate fullness pathways at once for bigger weight loss than either alone. It is still experimental.
What it's used for
A weekly two-in-one shot combining an appetite-lowering peptide with semaglutide, for bigger weight loss than either alone.
How does CagriSema work?
What it does in the body, and where.CagriSema is two drugs in one weekly injection: cagrilintide and semaglutide, at fixed doses. The logic is that two separate fullness pathways should add up.
- 01Semaglutide handles the GLP-1 sideAppetite, stomach emptying, blood sugar.
- 02Cagrilintide handles the amylin sideA different route to fullness, so the two do not compete for the same receptor.
- 03Fixed doses, titrated togetherBoth components rise on one schedule over roughly 16 weeks, so you cannot adjust one without the other.
- 04Filed with the FDA, not approvedThe application went in during December 2025. Until a decision, this remains investigational.
Hits 2 receptors at once.
What else is it used for?
Each use below carries its own evidence level. Approved means regulators have cleared it for that purpose. Investigational means it is in trials. Early research means it is being studied and is not established.

How much, and do you cycle it?
The range, and whether you take breaks.2.4 mg per week, weekly. Not cycled in the trialsTrial dose
Given continuously for the whole study period: REDEFINE 1, 68 weeks. The dose is stepped up at the start, which is a ramp rather than a cycle, and no trial in this class built in a planned break.
How do I dose and price it?
Enter your vial and your dose. Pick a mix. We show the draw and the cost.The vial holds a fixed amount of drug. Adding more water does not make more drug, it just spreads it thinner, so you draw a bigger number on the syringe for the same dose.

Measuring the water1 mL = one full 100-unit syringe.
Your draw
48 / 100 unitsHow do you store it?
Before mixing, and after.Dry powder in the freezer or fridge. Once mixed, fridge, and use within about a month.
Unmixed lyophilized CagriSema keeps for a long time cold. Once you add water the clock starts: most reconstituted vials hold up for roughly 28 to 30 days at fridge temperature. Keep it out of light, and do not freeze it after mixing.

Show glossary +
What these words mean
- Titrate
- Starting at a low dose and increasing it slowly over time so your body adjusts and side effects stay mild.
- Subcutaneous
- An injection just under the skin, into the fat layer, usually with a short, thin insulin needle.
- Intramuscular (IM)
- An injection into a muscle, using a longer needle.
- Reconstitution
- Mixing a powdered peptide with liquid (bacteriostatic water) so it can be drawn into a syringe.
- Bacteriostatic water
- Sterile water with a tiny amount of preservative, used to mix powdered peptides.
- Concentration
- How strong the mixed peptide is, in milligrams per milliliter (mg/mL). More water makes it weaker; less water makes it stronger.
- Units (on the syringe)
- The marks on an insulin syringe. 100 units equals 1 mL. They measure how much liquid you draw, not the dose in milligrams.
- mcg and mg
- Units of dose. 1 milligram (mg) equals 1,000 micrograms (mcg).
- GLP-1
- A natural gut hormone that lowers appetite and blood sugar. Drugs that copy it, like semaglutide, are used for weight loss.
- Growth hormone secretagogue
- A compound that nudges your body to release more of its own growth hormone, rather than injecting the hormone itself.
- Half-life
- How long a compound stays active in your body. A longer half-life means you inject less often.
- Peptide vs small molecule
- A peptide is a short chain of amino acids. A few items here (like MK-677 or methylene blue) are small molecules, not true peptides, but people use them the same way.
- Research only
- No approved dose or use in people. Sold for research and not reviewed by the FDA for safety or quality.
- Investigational
- Still being tested in clinical trials and not yet approved or legally sold for general use.
- Banned in drug-tested sport
- Prohibited by the World Anti-Doping Agency (WADA); using it can disqualify a competing athlete.
