Calculator · Your own numbers
Peptide cost calculator
Type how much is in the vial, your dose, and how often you take it. See how many doses the vial holds and when it runs out. Add the price you paid to see the cost of each dose.
Updated , by The Peptide Field Read our standards
Only a licensed clinician should set a dose. Talk with your doctor, nurse, or pharmacist before you use any number from this page. Ask them to work out the numbers on their own.
You use these results at your own risk. The Peptide Field is not liable for any dose measured or taken with them.
Doses and cost
Fill in: amount in the vial, dose you were told to use.
How the math works
Each dose uses part of the vial.
- Each dose takes the same amount out of the vial. Your schedule spaces those doses over the days.
- The vial runs out after its last full dose.
- Some labels say to throw a mixed vial away after a set time. Doses after the throw-away day are lost, even if liquid is left.
Before you use these numbers
- Have your provider check the math first. Show your doctor, nurse, or pharmacist the vial, its label, and the numbers you typed. Ask them to work it out on their own.
- Use the same unit as your instructions. Mixing up mg and mcg gives a dose 1,000 times too big or too small.
- Use a new, sterile needle and syringe for every dose. Never share needles or syringes, and keep each vial for one person. The FDA and CDC both say this.

What this calculator cannot do
- It cannot tell you what dose to use. Only a licensed clinician should set a dose.
- It cannot check that the vial holds the amount printed on its label.
- It cannot tell you if a product is safe, legal, or real.
- It works only for U-100 insulin syringes. U-40 syringes are marked differently, and the result would be wrong.
- It never turns IU into mg or mcg. That depends on the substance, so only the label can tell you.
Common questions
- Why are some dates marked about?
- A times-a-week schedule does not say which days. So the page can only give a close date. A schedule of every few days gives exact dates.
- What if the label says to throw the vial away after some days?
- Type that number of days. If the vial would run out later, the page warns you. It also shows the cost for only the doses you can use.
- Does the cost include water, syringes, or shipping?
- No. It counts only the price you type for one vial. Add other costs yourself if you want them counted.
- Can this calculator tell me what dose to use?
- No. It only does math with the numbers you type. Only a licensed clinician should set a dose.
