Don’t trust the label.
Verify the batch.
Research peptides held in UK stock, dispatched the same working day. Every batch number leads to a published Certificate of Analysis you can check yourself.
A good place to start.
Each product links to the certificate for its current batch. Add any two or more and the multi-item discount applies itself.
Four ways in. One standard throughout.
Whether you arrive to buy, to understand a compound, to learn the science or to check our testing, everything connects.
Research Peptides
Single compounds, peptide blends, research supplies and pre-paired stacks.
/products/ 02Research
Nine research areas, a profile for every compound, and side-by-side comparisons.
/research/ 03Research Library
Peptide science, how to weigh research evidence, laboratory methods and a glossary.
/library/ 04Quality & Testing
The certificate library, how HPLC and mass spectrometry work, and how to read a CoA.
/quality/Anyone can print “99%” on a label. We publish the certificate.
Every batch is tested for HPLC purity and mass spectrometry identity before release, and its Certificate of Analysis is published here under the batch number printed on the vial.
- HPLC for purity. Reported as a minimum, exactly as the certificate states it.
- Mass spectrometry for identity. Purity alone cannot prove what is in the vial.
- Batch-matched. The number on your vial is the number on the report.
