Understanding mg, mcg, and mL

mg (Milligram) = 1/1000 of a gram (measure of MASS/AMOUNT)

mcg (Microgram) = 1/1000 of a milligram (1 mg = 1000 mcg)

mL (Milliliter) = 1/1000 of a liter (measure of VOLUME)

Example: 1 mL Injectable with 10 mg Peptide

  • Total peptide in vial: 10 mg (or 10,000 mcg)
  • Volume: 1 mL
  • Concentration: 10 mg/mL (or 10,000 mcg/mL)
  • If you inject 0.1 mL: you get 1 mg (1000 mcg)
  • If you inject 0.01 mL: you get 0.1 mg (100 mcg)

Step-by-Step Reconstitution Example

1
You have: 10 mg lyophilized peptide in vial + sterile water (BAC water)
2
Add: 1 mL of bacteriostatic water to the 10 mg vial
3
Result: 10 mg/mL concentration (10,000 mcg/mL)
4
To inject 100 mcg: Draw 0.01 mL (10 units on insulin syringe)
5
To inject 250 mcg: Draw 0.025 mL (2.5 units on insulin syringe)
