Plan your quantities and costs.

Use your own known schedule and amount to estimate complete portions, required vials and the cost of additional stock.

Illustrative defaults only. This tool performs arithmetic and does not choose a dose, regimen or preparation method.

YOUR CALCULATION

The numbers, explained.

Planned events20
Total portions needed20
Total mass needed5 mg
Complete portions per vial20
Vials required1
Additional vials needed1
Unopened vials remaining0
Theoretical leftover mass (including partial remainders)0 mg

The first event is on day 1, then every entered interval through the plan’s last day. This is your entered schedule, not a recommended regimen.

Stock and cost estimates exclude losses, discard dates, taxes and shipping. They do not mean a prepared vial stays usable for the entire plan.

Check the formulas

Events = ceil(20 days ÷ 1-day interval) = 20

Portions = events × 1; portions per vial = floor(5 ÷ (250 ÷ 1,000))

Vials required = ceil(total portions ÷ complete portions per vial). Partial leftovers are not pooled across vials.
