  • 78–85%
  • 5 weeks synthesis to verification
  • 18–25%
  • Moderate complexity synthesis with solid batch consistency. January promotions clear Q4 verified stock before Q1 metabolic research compound batches begin.
  • Neuroprotective Compounds (Cerebrolysin, P21, Dihexa)
  • $145–$220/vial
  • $102–$154/vial
  • 65–75%
  • 6 weeks synthesis to verification
