About Peptra Labs
Our Story
Peptra Labs supplies peptides and related compounds for laboratory research. The lab reports we publish come from two independent laboratories, Janoshik and Liquilabs, and are listed per batch on our Lab Reports page.
Each record states the batch number, the test date and the tests that were run. If a test is not listed for a batch, it was not run on that batch.
Our Mission
Our aim is to make batches checkable. We publish what was tested and imply nothing about what was not, so a batch is judged on its own record rather than on a general promise.
- Independent purity testing, published whenever a report exists
- Lab reports open to anyone, without an account
- Documentation that states what was tested and what was not
- Research-use-only labelling on every product, without exception
- No claim on this site that our lab records cannot support
Quality Standards
Where a batch has been tested, these are the records we publish:
Purity Analysis
Purity testing to support batch-level quality review.
Third-Party Testing
Independent laboratory review supports batch-level quality assessment.
Additional Tests
Additional assay results are listed only when they exist for the relevant batch.
Certificate of Analysis Available
Available batch-level Certificate of Analysis information is accessible through our Lab Reports section.
Who we are and how we work
Peptra Labs is run by Nexus Research Laboratories EOOD, a company registered in Sofia, Bulgaria, in the European Union. Testing is done by independent laboratories, not in-house, and each published report is kept as a batch record that you can match against the number printed on your vial.
Our products are for research use only. They are not for human or veterinary use.
Our Commitment to Researchers
In practice, this means:
- Supplying sealed vials, labelled with the compound name and batch number
- Publishing lab reports as they are issued, and saying plainly where none exists
- Shipping with tracking within the EU, in a padded envelope, with each vial in its own bag
- Answering by email and WhatsApp, in English, Spanish and Romanian
- Keeping a Lab Reports page where you can look up the batch number printed on your vial
