Peptide Syringe Units Guide: mcg, mL and U-100 units
A Research Use Only guide to U-100 syringe units, mcg per unit, mL conversions and peptide reconstitution math. The goal is educational calculation, not medical advice or human-use instruction.
Short answer
A U-100 syringe means 100 units per 1 mL, so 1 unit equals 0.01 mL. Mcg per unit depends on vial mg and diluent mL. All calculations here are educational research arithmetic.
No example on this page is a recommended dose.
Core formulas
concentration mg/mL
vial mg / diluent mL
How many milligrams are present in each milliliter after reconstitution.
mcg/mL
mg/mL x 1000
Converts milligrams per mL into micrograms per mL.
mcg per unit
mcg/mL / 100
A U-100 syringe has 100 units per 1 mL, so each unit is one hundredth of a mL.
units for target mcg
target mcg / mcg per unit
Educational arithmetic only; not a dosing recommendation.
U-100 syringe basics
A unit on a U-100 syringe is a volume marker. Because 100 units equal 1.00 mL, each unit equals 0.01 mL.
10 units
0.10 mL
50 units
0.50 mL
100 units
1.00 mL
The peptide amount represented by those units changes with concentration. That is why vial amount and diluent volume must be known before mcg per unit can be calculated.
Simple educational examples
Example A: 5 mg vial + 2 mL diluent
5 mg / 2 mL = 2.5 mg/mL
- •2.5 mg/mL x 1000 = 2500 mcg/mL
- •2500 mcg/mL / 100 = 25 mcg per U-100 unit
- •250 mcg / 25 = 10 units
Example B: 10 mg vial + 2 mL diluent
10 mg / 2 mL = 5 mg/mL
- •5 mg/mL x 1000 = 5000 mcg/mL
- •5000 mcg/mL / 100 = 50 mcg per U-100 unit
- •500 mcg / 50 = 10 units
Example C: 2 mg vial + 1 mL diluent
2 mg / 1 mL = 2 mg/mL
- •2 mg/mL x 1000 = 2000 mcg/mL
- •2000 mcg/mL / 100 = 20 mcg per U-100 unit
- •100 mcg / 20 = 5 units

FAQ
What does a unit mean on a U-100 syringe?
On a U-100 syringe, 100 units equal 1 mL. One unit is therefore 0.01 mL. This guide uses that relationship only for educational concentration math.
How many mL is 1 unit?
One U-100 unit equals 0.01 mL. Ten units equal 0.10 mL, 50 units equal 0.50 mL, and 100 units equal 1.00 mL.
How are mcg per unit calculated?
First calculate concentration in mg/mL, then convert to mcg/mL by multiplying by 1000. Divide mcg/mL by 100 to get mcg per U-100 unit.
Why is mcg per unit not the same for every vial?
Mcg per unit changes whenever vial amount or diluent volume changes. A 5 mg vial in 2 mL and a 10 mg vial in 2 mL have different concentrations.
