Enter the vial amount and the volume of solvent added. The calculator shows the concentration, the mg held at every 0.1 mL mark on a 1 mL syringe, and the volume that contains any mg amount you need for an assay.
The standard adds vial mg ÷ 10 mL of solvent, so every 0.1 mL mark holds 1 mg. Make sure the volume fits your vial.

Enter an amount to see the volume that contains it.
Reconstitution spreads a fixed amount of lyophilized powder evenly through the solvent you add. Two numbers decide everything: the vial amount and the solvent volume.
The amount held in any volume is the concentration times that volume. For example, a 10 mg vial with 2 mL of solvent is 5 mg/mL, so each 0.1 mL mark holds 0.5 mg.
Adding vial mg ÷ 10 mL of solvent gives 10 mg/mL for any vial size. Every 0.1 mL graduation then holds exactly 1 mg, which keeps records simple across compounds.
| Vial | Solvent for 10 mg/mL |
|---|---|
| 2 mg | 0.2 mL |
| 5 mg | 0.5 mL |
| 10 mg | 1 mL |
| 15 mg | 1.5 mL |
| 20 mg | 2 mL |
| 30 mg | 3 mL |
| 50 mg | 5 mL |
Very small volumes are hard to measure accurately, and large ones may not fit the vial. In either case, choose a different volume and let the calculator do the arithmetic.
Every Central Coast Peptides vial is third-party tested for purity, with a certificate of analysis for its lot.
