Peptide price per milligram: how to compare fairly
Updated October 29, 2026. Example numbers are made up to show the method.
30-second answer
divide the price by the milligrams in the vial.
- A cheaper vial is not cheaper if it holds less.
The formula
Price per mg = price ÷ milligrams in the product.
| Example | Price | Amount | Per mg |
|---|---|---|---|
| Vial A | $60.00 | 5 mg | $12.00 |
| Vial B | $90.00 | 10 mg | $9.00 |
| Vial B with 10% code | $81.00 | 10 mg | $8.10 |
| Vial B, code + Bitcoin (28%) | $64.80 | 10 mg | $6.48 |
