Peptide mcg → Units Converter.
Vial + water → convert any mcg amount to U-100 syringe units.
How it works.
Set the concentration
Enter the vial size (mg) and how much bacteriostatic water you're adding (mL). That fixes how many micrograms sit in one U-100 syringe unit.
Convert either direction
Choose mcg → units or units → mcg and type an amount. The result updates instantly against the concentration you set.
Read mcg per unit
The concentration card shows mcg per unit so you can sanity-check the conversion. It never suggests an amount; you enter every number.
FAQ.
Why do I have to enter the vial and water?
Because a syringe 'unit' is a volume (0.01 mL on a U-100 syringe), not an amount of peptide. How many micrograms are in one unit depends entirely on the concentration you mixed, so the vial size and water volume have to come first.
Is this different from the reconstitution calculator?
It's the same underlying math, focused on the single mcg↔units conversion both directions. The full reconstitution calculator adds doses-per-vial, a visual syringe, a compound library, and volume comparisons.
