Quality & documentation
Every Met7 lot is HPLC and MS verified.
Research and clinical practice are only as reliable as the documentation behind the peptide on the bench. Met7 ships every batch with a Certificate of Analysis tied to the specific lot you received — purity by reverse-phase HPLC, identity confirmed by mass spectrometry, and full appearance and content data.
The Met7 quality stack
Six checkpoints between synthesis and your bench.
Solid-phase synthesis
Fmoc SPPS protocols with controlled coupling cycles. Each step monitored to keep deletion sequences and truncations to a minimum.
HPLC purity ≥ 99%
Reverse-phase HPLC on every lot. Target purity ≥99%; rejected batches never leave the facility.
Mass spectrometry identity
Molecular weight confirmed by MS (ESI / MALDI) against expected sequence. Every lot, no exceptions.
Cold-chain handling
Lyophilization, packaging and dispatch under controlled cold-chain. Shipments documented end-to-end.
Per-lot Certificate of Analysis
Each shipment is traceable to a specific lot with its HPLC chromatogram, MS spectrum, appearance and content data.
Korean cGMP process
Process aligned with South Korea's MFDS cGMP framework — documented QC, controlled environment, batch traceability.
Inside the lab
From synthesis bench to sealed vial — see how Met7 works.
A glimpse of the Korean facility, the lyophilization stage and the documentation that ships with every lot. Real operations, not stock imagery.
01 — FacilityControlled cleanroom
HPLC analysis under cGMP-aligned, MFDS-grade environmental controls.
02 — ProcessLyophilization
Vials freeze-dried under vacuum for long-term stability and cold-chain handling.
03 — DocumentationCertificate of Analysis
Every lot ships with its HPLC chromatogram and MS identity spectrum.

Certificate of Authenticity
Verify any Met7 lot in seconds.
Every Met7 COA ships with a unique QR code. Scan it — or paste the lot code here — to confirm purity, identity and manufacturing data directly against our database.
Third-party verification
Independent reviews welcome.
We work with independent peptide review platforms and welcome batch testing by third parties. If you operate a verification service or directory and want to evaluate Met7, we ship samples and provide the matching lot documentation.
For directory listings (PeptiChecks and similar review platforms), email us with the evaluation protocol and we will coordinate sample dispatch and COA delivery directly.
