mcg
Microgram. One millionth of a gram (0.001 mg or 1,000 nanograms). The standard unit for peptide dosing. Also abbreviated as µg. Most research peptides are dosed in the 100–1,000 mcg range.
Frequently Asked Questions
What is mcg?
Microgram. One millionth of a gram (0.001 mg or 1,000 nanograms). The standard unit for peptide dosing. Also abbreviated as µg. Most research peptides are dosed in the 100–1,000 mcg range.
Why is mcg important in peptide research?
Understanding mcg is essential for safe and effective peptide use. Proper administration technique directly impacts peptide bioavailability, therapeutic outcomes, and minimizes the risk of adverse effects or contamination.

IU
International Units. A standardized measurement used for some biologics and peptides, particularly growth hormone (1 IU = approximately 0.33 mg) and insulin. Conversion factors vary by substance.
Syringe unitsMeasurement markings on insulin syringes, where 100 units = 1 mL. Understanding syringe units is essential for accurate peptide dosing after reconstitution.
Dose titrationThe practice of gradually increasing a peptide dose over time to assess individual tolerance and find the minimum effective dose while minimizing side effects. Standard practice with GLP-1 agonists.
