Built by scientists, for serious research
We supply research laboratories, universities and independent investigators with analytically verified peptides. Our compounds are synthesised using solid-phase peptide synthesis, purified by preparative HPLC and independently tested before release.
- Independent HPLC & mass spectrometry testing
- Batch-level Certificates of Analysis
- Lyophilized for maximum stability
- Dedicated scientific support team
Trusted by research teams worldwide
Purity matched the COA exactly in our own HPLC run. Documentation is the most complete we have seen from a supplier.
Consistent batches, fast dispatch and cold packs every time. Our reconstitution results are reproducible across orders.
Being able to look up the lot number on the vial and download the exact certificate saves us hours of paperwork.
Frequently asked questions
Can't find your answer? Our scientific support team is happy to help.
Q01Are your products for human consumption?
No. All products are sold strictly for in-vitro laboratory research. They are not drugs, food or cosmetics and are not intended for human or animal use.
Q02How is purity verified?
Each batch is analysed by an independent laboratory using HPLC and mass spectrometry. The resulting Certificate of Analysis is published in our COA library.
Q03How should lyophilized peptides be stored?
Store lyophilized vials at -20°C, protected from light and moisture. Once reconstituted, keep refrigerated at 2–8°C.
Q04How fast do you ship?
Orders placed before 2 PM on business days are dispatched the same day in insulated, discreet packaging.
Q05Do you offer bulk pricing?
Yes — bundle pricing is applied automatically on product pages. For institutional volumes, contact our team for a quote.
