Quality assurance

Comprehensive COAs on every batch.

Most suppliers test for purity. We go further — verifying everything purity testing can't see.

01

HPLC purity

Purity ≥99%, full chromatogram on the COA.

02

Mass spectrometry

Confirms molecular identity and sequence.

03

Net content

Measured mg matches the label.

04

Heavy metals

Lead, mercury, arsenic, cadmium screened.

05

Microbiological

Bacterial and fungal contamination.

06

Residual solvents

Leftover synthesis solvents screened.

Why it matters

A compound can look pure and still carry contaminants.

Every certificate is generated by an independent, ISO 17025-accredited US lab and published at generalpeptide.com before any order is placed. Batch-specific. Never generic.
