Semax Amidate Quality Real vs Fake: Comparison
The table below compares authentic research-grade Semax Amidate against common counterfeit or low-quality variants across manufacturing, documentation, and physical quality markers. HPLC Purity 95–99% with single dominant peak and labeled impurities <90% purit
No winner is assigned.

- The table below compares authentic research-grade Semax Amidate against common counterfeit or low-quality variants across manufacturing, documentation, and physical quality markers.
- HPLC Purity
- 95–99% with single dominant peak and labeled impurities
- <90% purity, multiple unidentified peaks, or no chromatogram provided
- HPLC is non-negotiable. Batches without verifiable chromatograms should be rejected regardless of price
- Mass Spectrometry Confirmation
- Molecular weight 872.99 g/mol ±0.5 Da, single clean peak
- No MS data, or mass deviations >5 Da indicating wrong peptide or deletion sequences
- MS confirms you received the correct molecule. Absence of MS data means you have no idea what's in the vial
- Reconstitution Behavior
- Dissolves completely in 30–60 seconds, clear colorless solution, no particulates
- Incomplete dissolution, cloudiness, visible aggregates, or discoloration
- Reconstitution failure is immediate visual proof of compromised material. Do not proceed with research
- Certificate of Analysis (COA)
- Batch-specific with HPLC, MS, endotoxin (<1.0 EU/mg), sterility, and matching batch number on vial
- Generic recycled COA, missing key tests, or batch number mismatch
- COA traceability is the minimum standard. Unverified or mismatched documents indicate fraudulent sourcing
- Storage and Packaging
- Pharmaceutical-grade vials, crimp-seal closures, labeled with batch/date/storage conditions
- Generic screw-top vials, handwritten labels, no tamper seals, or missing storage guidance
- Packaging quality reflects manufacturing standards. Corners cut here signal corners cut in synthesis
- Endotoxin Testing
- <1.0 EU/mg via LAL assay, documented on COA
- No endotoxin data or levels >5.0 EU/mg
- Endotoxin contamination invalidates cell culture and animal model results. Untested batches are research liabilities
