“Cagrilintide acetate” is not a separate product from cagrilintide; it is the form in which the peptide is delivered after purification. This page explains what “acetate” means, the current status of cagrilintide as a pharmaceutical product, why it is not available in pharmacies, and the cost of research-grade cagrilintide, with supporting analysis.

The essentials
What does "acetate" mean?
A synthetic peptide carries electrical charges. At the end of its purification, it is associated with a counter-ion that neutralizes them: most often theacetate(derived from acetic acid) or trifluoroacetate (TFA). “Cagrilintide acetate” is therefore the full chemical name of the powder: cagrilintide in the form of an acetate salt.
This does not change the active molecule. The counterion, however, is a factor in the weighted mass of powder, which explains why an analysis report distinguishes between the measured quantity of peptide and the purity. On a vial sold as "5 mg," it is the quantity of cagrilintide that matters: Janoshik measured 4.92 mg in our batch.

| QuestionIs cagrilintide an authorized drug? | Answer by 29/10/2026No, neither in France nor in the European Union. |
| QuestionCan it be bought in a pharmacy? | Answer by 29/10/2026No: no pharmacy can dispense a product without marketing authorization. |
| QuestionCan a doctor prescribe it? | Answer by 29/10/2026No, not outside of clinical trials. |
| QuestionWhere is it being studied? | Answer by 29/10/2026At Novo Nordisk, alone and especially in combination with semaglutide (CagriSema). |
| QuestionWhat is being sold online under this name? | Answer by 29/10/2026Research cagrilintide, in lyophilized powder form, without medical use. |
Searches for "cagrilintide acetate without a prescription" or "pharmacy price" yield no results in pharmacies. Research cagrilintide is not a substitute for treatment; it is intended for laboratory use only.
What the tests say
Amylin is a hormone secreted with insulin that affects satiety. Cagrilintide is a modified version that lasts longer in the body, allowing for weekly administration in trials.guide to the cagrilintidedetails its mechanism.
- Alone: in a phase 2 trial published inThe LancetIn 2021 (Lau et al.), the highest dose resulted in a weight loss of 10.8% in 26 weeks, compared to 3.0% with placebo.
- With semaglutide (CagriSema): in the phase 3 REDEFINE 1 trial (NEJM, 2025), −20.4% in 68 weeks, compared to −3.0% under placebo.
These results pertain to experimental drugs monitored in clinical trials. For comparison with retatrutide and tirzepatide, see ourcomparative.
Price of cagrilintide acetate
| Format | Price | Price per mg |
|---|---|---|
| FormatCagrilintide 5 mg (PeptiLine) | Price69,90 € | Price per mg13,98 € |
Cagrilintide is significantly more expensive per milligram than retatrutide or tirzepatide: its synthesis is more complex (longer peptide, lipid chain). A much lower price, without an analysis report, should prompt verification of the vial's contents. The required checks are the same as for retatrutide: seerecognizing a reliable supplier.
Delivery costs €10, free for orders over €160. To refill the bottle:bacteriostatic water(€5) orReenactment Pack (14,90 €).

Frequently Asked Questions
What is the difference between cagrilintide and cagrilintide acetate?
None for the active molecule. “Acetate” refers to the counter-ion associated with the peptide after its purification: this is the full chemical name of cagrilintide powder.
Can cagrilintide acetate be purchased in pharmacies?
No. Cagrilintide is not authorized as a medicine in France or in the European Union: no pharmacy dispenses it and no doctor can prescribe it outside of clinical trials.
What is the price of cagrilintide acetate?
At PeptiLine, a 5 mg vial costs €69.90, or €13.98 per mg, with a published Janoshik ratio (99.836%). Delivery is €10, free for orders over €160.
Is cagrilintide effective on its own?
In a phase 2 trial (The Lancet, 2021), the highest dose resulted in 10.8% weight loss over 26 weeks compared to 3.0% with placebo. It is primarily studied in combination with semaglutide (CagriSema).
How to check the quality of a cagrilintide?
Request the batch analysis report and its verification key, then check it at janoshik.com/verify. Our batch MP-777CG101 was measured at 4.92 mg and 99.836% purity (report #244211).
