Cagrilintide at a glance

Amylin is a peptide hormone secreted by pancreatic beta cells alongside insulin. Cagrilintide, developed by Novo Nordisk under the code AM833, is an engineered amylin analogue carrying a fatty-acid side chain that associates reversibly with albumin, slowing its removal from the circulation. Further sequence changes were introduced to reduce the tendency of native human amylin to aggregate into fibrils. Its listed molecular formula is C194H312N54O59S2, giving a molecular weight of about 4409 g/mol.

Price and availability

TFC Peptides lists this kit of 10 vials at 5mg each (50 mg in total), shipped from Tianjin, China. The price is $75.00, or $1.50 per milligram of peptide. 17 brands sell Cagrilintide on GLP1 Forum Escrow, with a typical price of $1.73–$8.48 per mg (median $1.97); this listing is below the typical range, so among the cheaper options. As with every order here, the brand is paid only after you confirm delivery.

Lab testing

There is no public lab report for this listing yet. We can ask the brand for the batch COA before you order. Many buyers also split an independent HPLC test with others who bought the same batch.

Bought through escrow: the brand is only paid after you confirm delivery. If the parcel never arrives, or an independent test shows the wrong compound or a significant under-fill, open a claim before releasing payment.

What it is studied for

Amylin receptors are unusual: each forms when the calcitonin receptor pairs with one of the receptor activity-modifying proteins, RAMP1, RAMP2 or RAMP3. Cagrilintide is described as a nonselective agonist that activates these amylin receptor complexes and the calcitonin receptor itself. In animal and early human studies, signaling through hindbrain regions such as the area postrema has been linked to delayed gastric emptying, reduced food intake and lower post-meal glucagon. Because these pathways differ from GLP-1 receptor signaling, investigators examine the two classes side by side to separate their contributions to energy-balance endpoints.

Research and regulatory status

Clinical development has centered on the fixed combination with semaglutide, often called CagriSema, which has been evaluated in large late-stage obesity and type 2 diabetes trials. Cagrilintide on its own has been studied in a mid-stage weight-management trial. As of early 2026, neither the single agent nor the combination should be described as an approved medicine, and its regulatory position can change quickly, so readers should confirm it against current agency records. Mechanistic detail still relies heavily on rodent pharmacology.

Checking the lab data

Because cagrilintide is a large lipidated peptide, a convincing report pairs HPLC purity with high-resolution mass spectrometry showing a deconvoluted mass close to 4409 Da, which confirms the fatty-acid side chain is present. A missing or truncated lipid would show up as a lower mass. Peptide-content figures help when comparing listings per mg. Expect a white lyophilized cake; solutions prepared for analysis should be clear, and turbidity or gel-like residue suggests aggregation.

Storage and preparation

Keep unopened freeze-dried vials cold, sealed and out of the light; moisture is what degrades a lyophilized cake fastest. After reconstitution, refrigerate the solution and work within the stability window your protocol sets.

Concentration arithmetic: one 5 mg vial dissolved in 2 mL gives 2.5 mg/mL, or 5 mg/mL in 1 mL. The Research Lab calculator in your dashboard handles any other volume.

Buyer questions

What does the code AM833 refer to?

AM833 is the development code under which cagrilintide appeared in early clinical publications and trial registrations. Papers and registries may use either name, so searching both terms gives a more complete view of the literature. The code and the nonproprietary name describe the same molecule, not two related compounds.

Why did researchers engineer around native amylin's stability problems?

Human amylin readily clumps into insoluble fibrils, which complicates formulation and laboratory handling. An earlier analogue, pramlintide, addressed this with proline substitutions. Cagrilintide's design added further sequence changes plus a lipid chain, aiming for a molecule that stays soluble and persists in circulation far longer than the native hormone.

How much Cagrilintide is in this listing?

10 vials of 5mg each — 50 mg in all. Where a lab report exists, the testing panel above shows what the brand's tested sample actually measured.

When does TFC Peptides get paid?

Only after you confirm delivery. Until then the payment is held in escrow, and you can open a claim if anything is wrong with the order.
