- Certificate of Analysis (CoA)
- Issued by third-party lab with HPLC purity ≥98%, mass spec confirmation of ~4,800 Da molecular weight, and batch-specific data
- Generic CoA with no batch linkage, missing mass spec data, or purity claims without supporting chromatograms
- CoA proves chemical identity and purity. Without it, you're trusting a label claim with no verification
- Demand a batch-linked CoA before purchase; if the supplier can't provide one, walk away
- Lyophilized Powder Appearance
- White to off-white, uniform cake-like texture, vacuum-sealed with intact crimp seal and no moisture
- Discolored, granular, clumped, or shows moisture inside the vial; loose or misaligned crimp seal
- Visual defects indicate degradation, contamination, or improper storage. The peptide is compromised before you even reconstitute it
- Reject any vial with visual inconsistencies; proper peptide synthesis produces uniform lyophilized cakes every time
- Batch Tracking and Traceability
- Unique alphanumeric batch code laser-etched on vial, verifiable through supplier records, linked to synthesis date and expiration
- Adhesive labels that peel off, generic batch codes, or supplier refuses to confirm batch existence
- Traceability ensures accountability. If a batch fails, you can trace it back to the source and prevent reorders
- Verify batch codes before starting experiments; counterfeit suppliers can't produce verifiable records
- Reconstituted Solution Clarity
- Clear to slightly opalescent, no particles, sediment, or cloudiness after mixing with bacteriostatic water
- Cloudy, particulate matter visible, or solution doesn't fully dissolve
- Cloudiness or particles indicate incomplete synthesis, aggregation, or contamination. The peptide is not pure
- Test a small volume first; if the solution isn't clear, don't use it in your protocol
- Endotoxin Level (LAL Testing)
- <1 EU/mg as confirmed by Limulus Amebocyte Lysate assay
- No endotoxin data provided, or levels exceed 10 EU/mg
- Endotoxins trigger immune responses in cell and animal models, confounding results unrelated to the peptide's pharmacological action
- Always request endotoxin testing data; contaminated peptides invalidate experimental outcomes
- Price Relative to Market
- $280–$450 per 5mg vial from verified suppliers (reflects small-batch synthesis, purity testing, and quality control)
- <$150 per 5mg vial, or significantly below market average without explanation
- Peptide synthesis at ≥98% purity has fixed costs. Prices far below market indicate shortcuts in synthesis, testing, or storage
- Suspiciously low prices are the clearest indicator of counterfeit or substandard product
