Peptura is a trading name of Oraxis Research Ltd, a UK-registered company (Company No. 17157816) operating under English law.
Our Mission
To give the research community peptides it can trust without caveats: consistently pure, accurately characterised, and backed by analytical documentation anyone can read. Dependable results start with dependable inputs, and that is the whole point of Peptura.
Sample Certificate of Analysis
Retatrutide 10mg · Batch-matched CoA
Every vial, independently verified.
- No batch leaves us without passing an independent lab check first.
- The Certificate of Analysis sits openly on each product page, with no email wall in the way.
- Identity is confirmed by HPLC and mass spectrometry, and purity is reported to 0.1 percent.

Our Process
Synthesis
Peptides are synthesised using solid-phase peptide synthesis (SPPS) methodology.
Purification
Crude peptides undergo purification via preparative HPLC to achieve target purity levels.
Analysis
Purified compounds are analysed using analytical HPLC and mass spectrometry.
Quality Verification
Supplier quality documentation is reviewed and verified before products are released.
Documentation
Batch documentation covering purity, appearance, and molecular specification is linked to each product.
