Cagrilintide Lyophilized Powder
Cagrilintide 10 mg is a long-acting amylin analogue peptide developed for investigation in weight management and type 2 diabetes. It is not FDA-approved for any indication as of 2026 and is available only within clinical trials.
Cagrilintide was engineered to overcome the limitations of pramlintide, the only previously FDA-approved amylin-based therapy, which requires three injections daily due to its short half-life. Cagrilintide is a non-fibrillating amylin analogue with a half-life of approximately 159–195 hours, allowing for once-weekly subcutaneous administration. As a dual amylin and calcitonin receptor agonist, cagrilintide binds to AMY1R, AMY2R, AMY3R, and CTR, with structural studies revealing an amylin-like binding mode that induces distinct conformational dynamics at calcitonin-family receptors.
In clinical trials, cagrilintide has been studied both as a monotherapy and in combination with semaglutide (CagriSema). A 2021 Phase 2 dose-finding trial reported approximately 10.8% weight loss at 4.5 mg over 26 weeks as monotherapy. The REDEFINE Phase 3 program for the fixed combination CagriSema reported 20.4% weight loss at 68 weeks in adults with obesity without diabetes, and a New Drug Application was submitted to the FDA in December 2025. However, cagrilintide as a standalone agent remains investigational, and Novo Nordisk has not announced plans to seek approval for monotherapy.

Long-Acting Amylin Analogue
Endogenous amylin is a pancreatic hormone co-secreted with insulin that reduces eating and inhibits postprandial glucagon secretion. Its primary site of action is the area postrema in the hindbrain, from which signals propagate to the nucleus of the solitary tract and lateral parabrachial nucleus. Amylin binds to heteromeric receptor complexes composed of the calcitonin receptor and specific receptor activity-modifying proteins (RAMPs 1–3), forming three distinct receptor subtypes: AMY1R, AMY2R, and AMY3R.
Cagrilintide was developed through structure-activity relationship studies with the aim of generating a long-acting non-fibrillating amylin analogue with retained affinity for AMY3R. It is N-terminally acylated with a γGlu linker and a C20 fatty diacid moiety, which contributes to its extended half-life. Pharmacokinetic analysis in combination with semaglutide 2.4 mg showed cagrilintide doses of 0.16–4.5 mg had a half-life of 159–195 hours, with median time to maximum concentration of 24–72 hours.
In vivo studies demonstrate that cagrilintide reduces food intake and body weight by reducing relative fat mass while maintaining relative lean mass. These effects are accompanied by activation of neurons in the area postrema via amylin receptor subtypes 1 and 3.

As of 2026, cagrilintide is not FDA-approved for any indication and has never been approved for compounding under Section 503A or 503B. It has not appeared on any FDA bulk drug substance list. Cagrilintide is available only within the context of clinical trials and is not obtainable through licensed compounding pharmacies or by standard prescription.
Cagrilintide 10 mg vs Other Stealth Labs Peptides
Stealth Labs offers Survodutide and Mazdutide as other research peptides commonly referenced in metabolic research contexts. Unlike cagrilintide, which targets amylin and calcitonin receptors, survodutide and mazdutide are dual GLP-1/glucagon receptor agonists.
Compared to TB 500, which is a thymosin beta-4 fragment studied for tissue healing, cagrilintide is a metabolic peptide with a distinct mechanism of action targeting appetite regulation and energy homeostasis. Both are lyophilized powders requiring reconstitution, and neither is FDA-approved for human use.

Reconstitution & Handling
Cagrilintide is supplied as a lyophilized powder requiring reconstitution with an appropriate solvent such as bacteriostatic water or sterile saline. Once reconstituted, peptide solutions are more susceptible to degradation and should be stored refrigerated at 2–8°C. Avoid repeated freeze-thaw cycles, which can degrade the peptide and potentially increase immunogenicity risk.
Reconstitution should be performed gently by swirling rather than shaking to prevent denaturation or aggregation. A cloudy solution or visible particles may indicate incomplete dissolution, aggregation, or contamination and should not be used.
Managing Research Risks
Cagrilintide has been studied in clinical trials with a safety profile generally consistent with the amylin analogue and GLP-1 receptor agonist classes. Adverse events in trials were most commonly gastrointestinal, including nausea, vomiting, and diarrhea, though cagrilintide monotherapy has been noted to have less vomiting than GLP-1 receptor agonists in network meta-analysis. Injection-site reactions were more common with CagriSema compared to semaglutide alone.
Because cagrilintide is investigational only, no long-term safety data exist outside clinical trial settings. Products sold online under the name cagrilintide through research compound vendors are not FDA-regulated, have no verified manufacturing standards, and carry unknown contamination, dosing, and safety risks.
Post-Cycle Considerations
Cagrilintide is not a hormone and does not suppress endogenous testosterone production. No post-cycle therapy is applicable or necessary for cagrilintide alone. If cagrilintide is referenced alongside anabolic compounds in non-medical contexts, any PCT protocol would be determined by the other compounds, not by cagrilintide.

Potential Adverse Effects
In clinical trials, adverse events with cagrilintide were most commonly gastrointestinal, including nausea, vomiting, and diarrhea. Most adverse events were mild to moderate in severity. Network meta-analysis found that cagrilintide ranked best for serious adverse events and allergic reactions compared to semaglutide, while CagriSema exhibited the most favorable gastrointestinal tolerability profile.
Injection-site reactions were more common with CagriSema compared to semaglutide alone. Because cagrilintide remains investigational, no long-term safety data exist outside clinical trial settings, and cardiovascular outcomes data for cagrilintide are not yet available.
Conditions Requiring Medical Evaluation
As cagrilintide is not approved for any indication, there are no established contraindications in non-clinical settings. Clinical trial exclusion criteria have included history of type 1 or type 2 diabetes in some weight management studies, pregnancy or breastfeeding, and treatment with GLP-1 receptor agonist medications within specified washout periods.

What is Cagrilintide 10 mg used for?
Cagrilintide 10 mg is a lyophilized research peptide sold for laboratory use only. In clinical trials, cagrilintide has been investigated as a monotherapy and in combination with semaglutide for weight management and type 2 diabetes. It is not FDA-approved for any indication and is available only within clinical trials.
How often should Cagrilintide 10 mg be used?
In clinical trials, cagrilintide is administered as a once-weekly subcutaneous injection. Doses studied have ranged from 0.16 mg to 4.5 mg as monotherapy, with 2.4 mg being the dose used in the CagriSema combination. No dosing recommendation can be made for non-clinical settings, as cagrilintide is not FDA-approved.
Does Cagrilintide 10 mg require PCT?
Cagrilintide is a peptide, not a hormone, and does not suppress endogenous testosterone production. No post-cycle therapy is applicable or necessary for cagrilintide alone. If cagrilintide is referenced alongside anabolic compounds in non-medical contexts, any PCT protocol would be determined by the other compounds, not by cagrilintide.
What does cagrilintide do?
Cagrilintide is a long-acting amylin analogue that acts as a dual amylin and calcitonin receptor agonist. It binds to AMY1R, AMY2R, AMY3R, and CTR, with primary action at the area postrema in the hindbrain to reduce food intake and body weight. In animal studies, it reduces relative fat mass while maintaining relative lean mass.
How long does cagrilintide take to work?
Cagrilintide has a half-life of 159–195 hours, with median time to maximum concentration of 24–72 hours after subcutaneous administration. In clinical trials, weight loss effects were observed over treatment periods of 20 to 68 weeks. The time required to notice effects depends on the individual and the specific outcome being evaluated.
Is cagrilintide the best weight management peptide?
There is no single agent that is universally best. Cagrilintide as a monotherapy achieved approximately 10.8% weight loss at 4.5 mg over 26 weeks in Phase 2 trials, while the CagriSema combination achieved 20.4% weight loss at 68 weeks in Phase 3 trials. Cagrilintide is investigational only, and non-medical use falls outside approved indications.
What is the difference between cagrilintide and semaglutide?
Cagrilintide is an amylin analogue that targets amylin and calcitonin receptors, while semaglutide is a GLP-1 receptor agonist. The two mechanisms are complementary, and the combination CagriSema has shown superior weight loss compared to semaglutide alone. Cagrilintide remains investigational, while semaglutide is FDA-approved.
What is the difference between cagrilintide and tirzepatide?
Cagrilintide is an amylin analogue, while tirzepatide is a dual GIP/GLP-1 receptor agonist. In a Phase 3 trial, CagriSema did not meet the primary endpoint of showing non-inferiority on weight loss compared to tirzepatide 15 mg at 84 weeks, though it achieved 23% weight loss. Both are distinct compounds with different mechanisms of action.
Is 10 mg of Cagrilintide a lot?
A milligram amount cannot be classified as appropriate or excessive because cagrilintide is not FDA-approved and no non-clinical dosing information exists. It is also important to distinguish a total vial content from a dose. Cagrilintide 10 mg indicates the total peptide content per vial; that quantity does not by itself specify how much should be used in any research application.
What strength is Cagrilintide 10 mg?
Cagrilintide 10 mg is labeled at 10 mg of cagrilintide per vial. It is supplied as a lyophilized powder in a 2 mL vial.
Is Cagrilintide 10 mg lab tested?
Yes. A published laboratory report dated September 13, 2024 measured Cagrilintide 10 mg at 9.39 mg, equivalent to 93.90% of its 10 mg/vial label claim. The complete report can be viewed in the Lab Reports tab. Laboratory results apply to the tested sample represented by the individual report.
Can Cagrilintide 10 mg be stacked with other compounds?
Cagrilintide is not FDA-approved, and no clinical data exists to support any combination with other compounds outside of clinical trials. In clinical trials, cagrilintide has been studied in combination with semaglutide as CagriSema. Stealth Labs offers Survodutide and Mazdutide as other research peptides, but combinations with cagrilintide lack clinical validation.
