How the math works
- Cost per mg: vial price divided by the mg in the vial.
- Doses per vial: the mg in the vial divided by your dose in mg (1 mg is 1,000 mcg).
- Cost per dose: vial price divided by doses per vial.
- Cost per week: cost per dose times doses a week.
- Cost per month: cost per dose times the doses in 30 days (doses a week times 30, divided by 7).
Worked examples
Two sample vials, worked by hand. Prices here are examples, not today's prices.
| Vial | Dose | Doses a week | Cost per mg | Cost per dose | Cost per 30 days |
|---|---|---|---|---|---|
| $45 for 5 mg | 250 mcg | 7 | $9.00 | $2.25 | $67.50 |
| $60 for 10 mg | 2 mg | 1 | $6.00 | $12.00 | $51.43 |
Questions
Why does cost per mg matter more than vial price?
Vials come in different sizes. A cheaper vial can hold less, so the price per mg is the fair way to compare two vendors. Our peptide pages show the live per-mg range across vendors.
Does this include shipping?
Only if you add it. Put the vial price plus your share of shipping in the price box and every figure includes it.
Why is a month 30 days here?
So the figure is the same every time you check it. A calendar month can be 28 to 31 days, which moves the answer by a few percent.
What about bulk packs?
Enter the pack price and the total mg in the pack. The cost per mg and per dose come out the same way.
