The lab report behind every vial
Public certificates across every compound we carry. Eight assays per batch, run by an independent ISO/IEC 17025 accredited lab. Read them before you buy.
The certificate library
Every lot, published. Tap a card to shop it.
No certificates published yet.
Certificates appear here as soon as lots are tested and published. Nothing ships before its certificate does.
All products are supplied strictly for laboratory research use.
What’s on the label is what’s in the vial.
Every certificate here comes from an independent ISO/IEC 17025 accredited lab. No batch ships without one.

Accredited testing
Eight assays. Every batch.
The same panel runs on every certificate. Here is what each test proves.
Peptide Purity
HPLC · 214nm
Reverse-phase HPLC area normalisation quantifies the target peptide against every other peptide-related peak. Our release standard is 99%+ purity on every batch.
Net Peptide Content
HPLC quantitation
Measures the actual milligrams of peptide in the vial against the label claim, so 10mg on the label means 10mg in the vial.
Identity
HPLC-MS/MS
Retention-time match against a certified reference standard confirms the compound is exactly what the label says it is.
Appearance
Visual inspection
The lyophilised cake or solution is inspected for colour, uniformity, and physical integrity before release.
Fentanyl Screen
LC-MS/MS
Every batch is screened for fentanyl and other controlled-substance adulterants as a supply-chain integrity control. Result on every certificate: not detected.
Heavy Metals
ICP-MS
Arsenic, cadmium, lead, mercury, and chromium quantified by mass spectrometry against strict screening limits.
Sterility
PCR / bioburden
PCR-based microbial detection verifies no bacterial or fungal growth in the vial.
Endotoxin
LAL kinetic
Bacterial endotoxin quantified in EU/mL by the kinetic LAL method and reported on every certificate.
Questions, answered.
A signed report from an analytical laboratory describing what a specific lot of material actually contains. It names the lot, the date tested, the methods used, and the result of each assay.
