Frequently Asked Questions

Answers to the questions our researchers ask most frequently, all in one place.

🛡 Are your products independently tested?

Yes. Every batch is verified using HPLC analysis by Janoshik Analytical.

Each batch we supply is independently tested by Janoshik Analytical, an unaffiliated peptide analysis laboratory based in the Czech Republic. HPLC testing consistently reports purity levels exceeding 99%.

Where a Certificate of Analysis (COA) is available for the current batch, a printed copy is included with your order. If a printed certificate has not yet been issued, the latest batch verification can be viewed on our Purity page.

Every COA contains a unique verification code that can be authenticated directly through Janoshik’s verification portal, allowing independent confirmation of the report. We also publish a guide explaining how to interpret Janoshik HPLC certificates.

💧 Reconstituting BAC Water and Lyophilised Powder

Follow these four simple steps:

1. Clean the vial stopper using one of the supplied alcohol wipes and allow it to dry.
2. Draw 2 mL of bacteriostatic water into an insulin syringe.
3. Slowly inject the diluent down the inner wall of the peptide vial, avoiding direct contact with the powder.
4. Gently swirl until the powder has completely dissolved. Do not shake. Refrigerate immediately after reconstitution.

The quick-reference reconstitution guide printed inside the box lid can be used for future preparations.

💉 Using the Pen

Attach a Fresh Needle

Disinfect the pen tip using an alcohol wipe before attaching a new sterile needle supplied in the kit.

Prime the Pen

Rotate the dose selector by one click, point the pen upwards and press the injection button. A small droplet appearing at the needle tip confirms the pen is primed and any trapped air has been removed.

Select the Required Research Dose

Each click on the dial delivers a fixed increment, typically 0.5-1 mg depending on the pen calibration. The dose window displays the total selected dose. As an example, a 6 mg research dose usually corresponds to approximately 6-12 clicks.

Administration

Published research protocols commonly describe subcutaneous administration into the abdomen, thigh or upper arm. Hold the pen in position for approximately six seconds before withdrawing.

Dispose of the used needle in an approved sharps container, replace the cap and return the pen to refrigerated storage.

Each pen delivers the number of doses shown in the protocol guide for your selected size. When empty, simply replace the cartridge while continuing to use the same pen body. Current refill pricing is available using the calculator above.

📍 Administration Route Reported in Published Research

Published pharmacokinetic and Phase II/III studies involving Cagrilintide commonly report subcutaneous administration into the abdomen, thigh or upper arm. Administration sites are typically rotated throughout the study to minimise local tissue irritation.

Research use only. The information above summarises published peer-reviewed literature for scientific reference only. We do not provide dosing recommendations, administration instructions or medical advice.

🎯 Which Research Dose Should Be Used?

The recommended approach is to follow the protocol guide shown above. Published Cagrilintide research generally follows a gradual titration schedule, beginning with the lowest study phase before increasing the dose at predetermined weekly intervals. The highlighted maintenance phase reflects where many research cohorts remain during ongoing investigation.

Researchers new to this compound should begin with Phase 1, complete the full protocol period, and then progress to the next phase. Gradual dose escalation mirrors the methodology described in published studies and is intended to reduce gastrointestinal events reported during clinical research.

Researchers already familiar with Cagrilintide can select their current protocol phase to view expected product duration and cost based on the chosen vial or pen size.

If your laboratory follows a customised protocol, contact us before ordering and we’ll help identify the most suitable product size for your research schedule.

Laboratory Handling

Cagrilintide is supplied as a freeze-dried powder in a sealed glass vial.

For laboratory reconstitution:

• Slowly introduce the required volume of bacteriostatic water down the inside wall of the vial.
• Avoid directing the liquid onto the peptide powder.
• Gently swirl until the contents have dissolved completely.
• Do not shake or vortex.
• Store the prepared solution at 2-8°C.
• Use within approximately 4-6 weeks, unless your laboratory protocol specifies otherwise.

Our Reconstitution Volume Calculator can be used to determine the resulting concentration (mg/mL).

State	Storage Temperature	Typical Shelf Life
Lyophilised	2-8°C or -20°C	Up to 24 months
Reconstituted	2-8°C	Approximately 4-6 weeks
