  • Milligrams (mg)
  • Absolute mass of compound
  • 1 mg = 1,000 mcg; IU conversion requires peptide-specific standard
  • General dosing, reconstitution calculations, inventory tracking
  • Most straightforward for mass-based protocols; always adjust for purity percentage from COA
  • Micrograms (mcg)
  • 1,000 mcg = 1 mg; IU conversion requires peptide-specific standard
  • Precision dosing, low-dose protocols, injection volume calculations
  • Preferred unit for sub-milligram doses to reduce decimal errors; verify syringe accuracy at target volume
  • International Units (IU)
  • Biological activity (receptor binding, enzymatic rate)
  • Mass conversion requires WHO/regulatory reference standard lookup
  • Protocols requiring bioactivity standardisation across batches
  • Only applicable if peptide has established IU standard; cannot be extrapolated from other peptides
