Syringe guide
Insulin syringes come in three common sizes. They all hold 100 units per mL, but their lines are spaced differently. Pick a size to see what each line means.

Optional: add your mix to see how much peptide each line holds.

How it works
- 30-unit (0.3 mL): usually marked every half or one unit. Best for small doses.
- 50-unit (0.5 mL): usually marked every unit.
- 100-unit (1 mL): usually marked every two units. Holds the most, but small draws are harder to read.
Markings vary by brand, so always check the box. Read the line at the top edge of the plunger's seal, not the tip.
This tool does arithmetic on numbers you enter. It does not suggest or check doses. Your dose and how to mix it come from your healthcare professional.
