  • This table compares Real Peptides Cartalax against typical competitor offerings across manufacturing standards, testing protocols, and supply chain transparency.
  • Synthesis Method
  • Small-batch SPPS with Fmoc chemistry
  • Large-scale Boc synthesis
  • SPPS, method unspecified
  • Small-batch SPPS
  • Real Peptides matches premium vendors. Small-batch synthesis reduces error rates and allows batch-specific quality control
  • Purity Verification
  • HPLC + mass spectrometry + CoA with chromatogram
  • Purity claim only, no CoA
  • HPLC CoA on request
  • HPLC + mass spec + amino-acid analysis
  • Real Peptides provides full analytical verification standard to premium tier. Competitors often omit mass spec
  • Endotoxin Testing
  • LAL test, <1 EU/mg verified
  • Not tested
  • LAL test included
  • Endotoxin testing is rare outside premium suppliers. Real Peptides includes it by default
  • Storage & Shipping
  • -20°C storage, insulated 48-hour cold shipping
  • Ambient shipping, no cold chain
  • Cold packs included, no insulation
  • Temperature-monitored shipping
  • Real Peptides shipping protocol prevents temperature excursions that cause degradation. Budget vendors skip cold chain entirely
  • CoA Transparency
  • Provided with every order, includes HPLC chromatogram and mass spec
  • No CoA unless requested
  • CoA available on request, limited detail
  • Full CoA with all analytical data
  • Real Peptides automatically includes comprehensive CoA. Competitors make it optional or provide summary-only documents
  • Batch Traceability
  • Batch number on every vial, linked to CoA
  • No batch tracking
  • Batch number on label, CoA separate
  • Full batch traceability
  • Real Peptides batch tracking allows verification of specific synthesis run. Essential for research reproducibility
