Peptide Dosage Reference

Updated April 16, 2026

Dosage Reference Guide

This reference covers dosage calculation fundamentals for peptide research. All doses are for research purposes only.

Syringe Reading

Standard U-100 insulin syringes measure in units (IU marks) where 100 IU = 1 mL. So 0.05 mL = 5 IU on syringe markings, and 0.25 mL = 25 IU.

Concentration Formula

Concentration = Peptide Amount (mg) ÷ Solvent Volume (mL)

Example: 5 mg peptide + 2 mL BAC water = 2.5 mg/mL concentration.

Volume to Inject

Volume = Target Dose (mg) ÷ Concentration (mg/mL)

Example: 250 mcg dose (0.25 mg) ÷ 2.5 mg/mL = 0.1 mL = 10 IU on syringe.
