Third-party testing
How batch testing will work
We are setting up independent lab testing for the compounds we sell. The lab will check two things: how pure the compound is, and that it really is the compound on the label. Each report will be published here against the batch number printed on the vial.
Status: no reports published yet
We have not published any lab reports yet. Testing is being arranged, and each report will go up on this page as it comes back. Email us if you would like to be told when the first one is published.
What the lab checks
Two tests, one report per batch
Purity by HPLC
High-performance liquid chromatography separates the sample and measures what share of it is the target peptide.
Identity by mass spec
Mass spectrometry weighs the molecule and confirms it matches the expected structure, so the vial holds what the label says.
Batch traceability
Each vial carries a batch number. Its report is posted here, so you can check the exact material you received.
Inside each report
What you will be able to check
- Name of the testing lab and the test date
- Batch number that matches the vial label
- Purity result as a percentage
- Mass-spec identity result
- The chromatogram from the lab
From arrival to report
How a batch will be tested
1. Batch arrives
New stock is logged in London and given a batch number.
2. Samples go out
Sealed vials from that batch are sent to the independent lab.
3. Lab runs the tests
HPLC for purity and mass spectrometry for identity.
4. Report goes up
The full report is posted here and linked to the batch.
Research use only
Everything we sell is for laboratory research and analytical use. It is not for human or veterinary use, and it is not a medicine, food or supplement. Test reports describe the identity and purity of the material, nothing more.
