Read the lot first.

Identity confirmed

LC-MS confirms the molecule in the vial is Semaglutide.

Purity measured

The same LC-MS run measures the share that is the target peptide.

Endotoxin screened

A LAL screen checks bacterial endotoxin against a limit.

Lot-linked report

Each report names the lot it was run on.

Each lab report is tied to its lot.

Reports are issued by BioRegen, an independent lab, and name the lot they were run on.

From synthesis to a published report

The five steps behind every certificate.

See how we test
Step 1

Synthesis and lyophilization

Synthesized and freeze-dried in US facilities, then given a lot number.

Step 2

Samples go to the independent lab

Finished vials from the lot are sent to BioRegen.

Step 3

LC-MS: identity, purity, net content

One run confirms the molecule and measures its purity.

Step 4

LAL endotoxin screen

Bacterial endotoxin is checked against a 0.5 EU/mL limit.

Step 5

Certificate published

The summary goes on the product page; full PDFs are for signed-in researchers.

Store at 2 to 8 °C. Keep sealed and away from light until use.
