SS-31 Real vs Fake: Supplier Comparison

Third-Party COA Provides batch-specific COA from named independent lab (e.g., SGS, Eurofins) with HPLC ≥98%, mass spec confirmation, endotoxin testing No COA, or 'in-house' purity report with no external lab listed COA from a named third-party lab is the singl

  • Third-Party COA
  • Provides batch-specific COA from named independent lab (e.g., SGS, Eurofins) with HPLC ≥98%, mass spec confirmation, endotoxin testing
  • No COA, or 'in-house' purity report with no external lab listed
  • COA from a named third-party lab is the single most important verification. Without it, there is no evidence the vial contains what the label claims
  • Business Transparency
  • Published physical address, phone contact, business registration, GMP compliance documentation
  • No physical address, encrypted-app-only contact, cryptocurrency-only payments, refuses to disclose location
  • Legitimate suppliers operate transparently. Vendors who hide their location or refuse standard payment methods are statistically more likely to sell counterfeit product
  • Reconstitution Behavior
  • Dissolves completely in <90 seconds, clear colorless solution, no particles or cloudiness
  • Does not dissolve, leaves suspension, cloudy or discolored solution post-reconstitution
  • Reconstitution is a bench-level diagnostic. If the peptide does not dissolve cleanly, it is degraded, contaminated, or not a peptide at all
  • Pricing Relative to Market
  • $120–$180 per gram (reflects actual synthesis cost for D-amino acid incorporation and purification)
  • <$60 per gram (below cost of legitimate synthesis)
  • Pricing far below market average is the clearest signal of underdosing or counterfeit product. Legitimate peptide synthesis has a floor cost
  • Batch Consistency
  • Slight purity variation across batches (97.5–99.2%). Reflects real synthesis variation
  • Identical purity across all batches (e.g., always exactly 98.7%). Statistically improbable, suggests fabricated COAs
  • Real peptide synthesis produces slight batch-to-batch variation. Identical results suggest data fabrication, not quality control
