← Full peptide calculator
Free tool
Enter the price you paid for a vial and your dosing to see the real cost per dose, per week, and per month. It works for any peptide or GLP-1 — the price is the one you enter, and this tool sells nothing and links to no vendor. Reference math, not medical or purchasing advice.
Cost per mg = vial price divided by vial mg; cost per dose = cost per mg times your dose. Monthly figure uses 4.345 weeks per month. Currency defaults to US dollars — switch to € or £ if you prefer; the number is whatever you enter. This tool sells nothing, links to no vendor, and does not recommend a source, product, or dose. Arithmetic only, not medical or purchasing advice.
Frequently asked questions
How is cost per dose calculated?
Cost per mg is the vial price divided by the vial strength in milligrams. Cost per dose is that cost per mg multiplied by your dose in milligrams (a dose entered in mcg is divided by 1000 first). Doses per vial is the vial strength divided by the dose.
How do I compare two vials of different sizes?
Normalize both to cost per mg, which is the price divided by the milligrams in the vial. The vial with the lower cost per mg is cheaper per unit of peptide, whether it is a 5 mg or a 10 mg vial.
Why can a cheaper vial still cost more per month?
Because your dose and how often you inject decide how many doses a vial gives you. A larger or cheaper-looking vial used at a higher dose or more frequently can work out more expensive per month than a smaller one. The monthly figure here uses 4.345 weeks per month.
Does the price include shipping, tax, or bacteriostatic water?
Only if you include them. The tool does arithmetic on the numbers you enter, so put your all-in vial price in the price field if you want shipping, tax, or diluent reflected in the cost per dose.
Is this medical or purchasing advice?
No. It is arithmetic and reference only. It does not recommend a product, a dose, a vendor, or a place to buy anything, and it does not judge whether a price is fair or a product is legitimate. Verify dosing with a clinician.
