Cagrilintide

Also known as: AM833

Cagrilintide is an investigational long-acting amylin analogue being studied for weight management, often in combination with semaglutide as CagriSema. It is not an approved medicine.

Claimed effects

The following effects are reported or claimed by users and in early research. They are not established medical facts and many are not supported by large human trials.

  • Reported in trials to support weight reduction, particularly when studied with semaglutide
  • Reported to reduce appetite and promote a sense of fullness
  • Reported to slow gastric emptying in study settings

How it is reported to work

Cagrilintide is described as a long-acting analogue of amylin, a hormone co-secreted with insulin that influences satiety and gastric emptying. By mimicking amylin signalling it is proposed to reduce food intake. These actions are reported from clinical research and are not those of an approved therapy.

Background

Cagrilintide is an investigational amylin analogue studied for weight management. It is frequently discussed alongside semaglutide as part of the combination known as CagriSema. Cagrilintide is not an approved medicine. This page is educational and is not medical advice; it does not recommend use.

What the research shows

Clinical trials have reported effects on body weight, especially when cagrilintide is studied together with semaglutide. These are reported research findings, not established outcomes of an approved product, and results may evolve as further trials report.

What people use it for (reported)

In research discussion, cagrilintide is reported to be of interest for appetite and weight outcomes, particularly because it targets a different pathway (amylin) than the widely discussed GLP-1 medicines. As an investigational compound there is no approved indication anywhere. Material described online as “cagrilintide” is not a verified, approved product, so its identity, purity and contents cannot be assumed, which is why independent testing is discussed in this space.

Things to be aware of

Because cagrilintide is unapproved and experimental, its long-term safety is not established, and the effects reported in trials may not reflect what is sold informally. Reported effects on this page are not confirmed facts; they summarise what research and discussion describe. Anyone with weight or metabolic concerns should consult a qualified healthcare professional for individualised guidance. This article is educational, does not recommend any dose, and does not direct anyone to obtain or use it.

Reported positives & side effects

Compiled from research and community reports. These are reported outcomes, not guarantees or medical advice, individual experiences vary widely.

Reported positives

  • Reported in trials to support weight reduction, particularly with semaglutide
  • Reported to reduce appetite and promote a sense of fullness
  • Reported to slow gastric emptying in study settings
  • Reported to complement incretin drugs via a separate amylin pathway

Common side effects

  • Reported nausea, especially during dose escalation
  • Reported vomiting or diarrhoea
  • Reported constipation and reduced appetite
  • Reported injection-site reactions

Rare / serious side effects

  • Theoretical pancreatitis risk shared across appetite-suppressing injectables
  • Reported gallbladder-related events with rapid weight loss
  • Reported dehydration from severe gastrointestinal effects
  • Reported allergic-type reactions to impurities in unverified product

Reported misuse & overdose risks

What has been reported to happen with overuse, excessive dosing, or long-term misuse of Cagrilintide. Listed so you can make an informed decision, not to suggest any use is safe.

  • Because it is investigational, self-dosing outside trials is reported to risk dehydration and electrolyte loss when persistent nausea and vomiting go unmanaged.
  • Skipping gradual escalation is reported to provoke severe GI effects and reports of inadequate nutrient intake.
  • Combining it with potent incretin drugs without supervision is reported to compound appetite suppression to the point of excessive, rapid weight loss and muscle loss.
  • Reliance on unverified research-grade vials is reported to carry dosing-error and contamination risks given no approved standalone formulation.

Reported results timeline

Roughly how long people report it takes to notice effects. A general guide from reports, not a promise, and not advice. Appetite and fullness effects are reported within days, with weight changes reported to develop over months in trial settings.

  1. First effects

    Reported early appetite suppression within days

  2. Noticeable change

    Reported early weight and fullness changes

  3. Clear results

    Reported meaningful weight reduction in trials

  4. Peak effect

    Reported continued reduction over longer trial periods

Commonly reported dosing & protocol

Reported figures only, NOT a recommendation or dosing advice. These are numbers people report using, compiled for education so you can make an informed decision. We do not advise anyone to take Cagrilintide. Many peptides are not approved for human use in Australia. Speak to a qualified healthcare professional.

Commonly reported dosing for Cagrilintide
RouteSubcutaneous injection
Typical reported doseInvestigational and NOT approved. Trial-reported doses range roughly 0.3–2.4 mg per week, reached by gradual titration
FrequencyReported as once weekly in trials
Cycle lengthTrials run over many months with stepwise dose escalation; no established consumer cycle

Reported reconstitution (mg → units)

Illustration only: a 5 mg vial + 1 mL bacteriostatic water = 5 mg/mL. A 1 mg dose is about 0.2 mL = 20 units on a U-100 insulin syringe.

Work out the units for your vial → Calculator

Reported in trials as a once-weekly injection with gradual escalation over months, sometimes paired with semaglutide as CagriSema; framed as trial-derived reporting, not advice. Not approved by the TGA or other regulators.

Best used with / commonly stacked with

Combinations people report using together. Reported, not recommended, stacking can increase risks.

Semaglutide

Reported together as CagriSema to combine amylin and GLP-1 pathways

Tirzepatide

Reported as a comparator incretin agonist in weight discussion

Retatrutide

Reported in discussion of layering amylin with multi-receptor agonists

Safety notes

Cagrilintide is an experimental compound without regulatory approval, so its complete safety profile is not established. Reported effects come from controlled trials. Anyone considering weight-management treatment should consult a qualified healthcare professional; cagrilintide is not an approved product in Australia.
