Tested. Verified.
Documented.
Every PrimeLine Labs lot moves through a defined analytical workflow and independent verification before it reaches a researcher's laboratory.
Our Testing Methodology
Two complementary analytical techniques confirm both purity and identity for every batch.
HPLC
High-performance liquid chromatography separates and quantifies components to confirm purity, typically ≥98–99%.
LC-MS/MS
Liquid chromatography tandem mass spectrometry confirms molecular identity and mass to the expected value.
Third-Party Labs
Independent U.S. laboratories re-verify results, removing any single point of bias from the data.
The quality
workflow
Quality is not a single checkpoint — it is a chain of verification steps, each documented and traceable to a lot number printed on your vial.
- Synthesis under controlled conditions
- In-house HPLC purity screening
- LC-MS/MS identity confirmation
- Independent third-party verification
- Certificate of Analysis issued per lot
- Cold-chain packaging and dispatch
Every lot, fully documented
Each peptide carries its own Certificate of Analysis — purity, identity, mass, and third-party validation — published directly on its product page and matched to your lot number.
