How it works

  1. 1
    Tell it what's in the vial
    Peptide mode takes total mg. Oil mode takes vial size (mL) × concentration (mg/mL) and computes the total for you.
  2. 2
    Enter amount + frequency
    Your amount per administration and how many times per week. Add the vial price for cost figures.
  3. 3
    Read longevity + cost
    Doses per vial, weeks and days per vial, and — if you entered a price — cost per dose and per week.

FAQ

How long will my vial last?

Doses per vial = total amount in the vial ÷ your amount per administration. Weeks per vial = doses ÷ administrations per week. The calculator computes both live, in peptide (total mg) or oil (mL × mg/mL) mode.

How do I work out cost per dose?

Cost per dose = vial price ÷ doses per vial. Enter the price and the tool shows cost per dose and per week, so you can compare vial sizes and concentrations.

Does it work for oil-based vials?

Yes — switch to oil mode and enter the vial size in mL and the concentration in mg/mL. It multiplies them to get total mg, then runs the same longevity and cost math.

Is this medical advice?

No. It's arithmetic on values you enter — no recommendation of any amount, frequency, or product. Educational only.
