Mass · mg & mcg
How much compound is present. One milligram equals 1,000 micrograms. The vial’s total mass is different from an amount you choose to calculate.
Peptide vial calculator
Connect the amount in your vial to concentration, liquid volume, and the marks on a syringe. One set of inputs. A result you can see.
Mass, volume, and syringe markings — clearly connected.
Import a single vial’s effective price where a verified automatic promotion applies; otherwise use its listed USD price, or enter your own below. Prices exclude shipping. Confirm the product label, promotion terms and current price.
Enter the quantities from your own research. Each value stays connected to the result.
Enter the vial amount, solution volume, and amount to calculate.
U-100 is a volume scale: 100 units = 1 mL. These markings are not milligrams or biological IU.
Vial yield is theoretical and excludes liquid left in the vial or syringe. A whole-number count is rounded down; the calculated volume is never rounded to a syringe marking.
This tool calculates mass, concentration, volume, and cost from your inputs. It does not recommend a dose, diluent, schedule, or administration method. Verify the label, units, and arithmetic independently.
Know your units

How much liquid is present. Concentration connects mass to volume: milligrams divided by milliliters.
A U-100 syringe has 100 scale units per mL. Check its capacity and smallest marking; the illustration is a scale guide, not an actual-size measuring tool.
