By placing an order through our website, you confirm that you are at least 18 years old and that all products purchased will be used strictly for legitimate laboratory, analytical or scientific research purposes.
We reserve the right to cancel or refuse an order if we have reason to believe these requirements have not been met.
How are peptides synthesised?
Peptides are created by linking amino acids together through peptide bonds to form a specific amino acid sequence.
In laboratory settings, one of the most common production methods is solid-phase peptide synthesis (SPPS). This typically involves:
- Attaching the first amino acid: The initial amino acid is secured to a solid support.
- Adding further amino acids: Additional amino acids are introduced one at a time in the required sequence.
- Repeating the process: The cycle continues until the desired peptide sequence has been formed.
- Final processing: The completed peptide is separated from the solid support before undergoing purification and further analysis.
This controlled process allows peptides with specific sequences to be produced for laboratory and scientific research purposes.
Do your peptides contain mannitol?
Yes. Our peptide products may contain small amounts of mannitol as an excipient.
Mannitol is commonly used during the lyophilisation process to support the physical properties of the finished freeze-dried product. It can help with:
- Product stability: Supporting the structure of the lyophilised material.
- Consistency: Helping create a more uniform freeze-dried product.
- Handling: Improving the physical characteristics of the material within the vial.
- Visibility: Providing a more visible lyophilised cake within the vial.
The presence of mannitol is normal and forms part of the preparation of our research products.
What are the best practices for handling and storing peptides?
Peptides can be sensitive to moisture, temperature and environmental conditions, so careful handling is important.
For lyophilised research products, we recommend:
- Allowing the sealed vial to reach room temperature before opening to help reduce condensation.
- Minimising exposure to moisture and air during laboratory handling.
- Keeping containers securely sealed when not in use.
- Following the storage information provided with the individual product.
Lyophilised peptides are generally more stable than peptides once prepared in solution. Storage requirements can vary depending on the individual peptide, solvent and intended laboratory application.
Always refer to the relevant product information and Certificate of Analysis where available.
All Pirate Peptides products are supplied strictly for laboratory and scientific research purposes only.

How are your peptides shipped?
Our peptides are supplied and shipped in their lyophilised (freeze-dried) form.
Secure Packaging:
Products are carefully packed to help protect the vials during transit and reduce unnecessary exposure to environmental conditions.
Protection During Transit:
Packaging is designed to minimise direct exposure to sunlight and provide suitable protection throughout the delivery process.
After Delivery:
Once received, products should be handled and stored in accordance with the storage information provided for the individual product.
Storage requirements can differ between lyophilised products and prepared laboratory solutions, so researchers should follow appropriate laboratory procedures for the specific compound being studied.
If you require further information about an order, product or delivery, please contact our team.
What happens after I make a payment?
Once your payment has been successfully received, your order will move into processing.
To keep our dispatch process efficient, we do not normally send individual payment confirmation messages beyond the automated order updates provided by our website.
Once your order has been processed and dispatched, you will receive a confirmation email along with tracking information where applicable.
Do you offer blended peptides?
No. We currently supply our peptides individually rather than offering pre-blended combinations.
Supplying individual products gives researchers greater control over the compounds, quantities and ratios used within their own laboratory protocols.
Pre-blended products can restrict this flexibility because the ratio between compounds has already been determined during manufacture. Keeping products separate also makes it easier to identify, document and assess each individual research material.
For this reason, we believe individually supplied peptides provide a more flexible option for laboratory and scientific research.
Can I get a Certificate of Analysis (CoA) for your products?
Yes. Certificates of Analysis (CoAs) are available for our products.
Where available, you can access the relevant CoA directly from the individual product page by selecting the Certificate of Analysis option and downloading the PDF.
Certificates of Analysis provide information relating to the tested product or batch and are supplied for reference and verification purposes.
CoA documents must not be altered, edited or misrepresented in any way.
