Peptide Cost Calculator
Educational tool to normalize pricing by delivered cost per mg.

Why Cost Per Milligram Matters
Research peptides are sold in a wide range of vial sizes and price points. A vial advertised at a lower sticker price may actually cost more per milligram once you factor in shipping. This calculator normalizes every offer to a single metric — delivered cost per mg — so you can make an apples-to-apples comparison across vendors and vial sizes.
How to Use This Calculator
- Enter the vial size in milligrams. Common sizes are 5 mg, 10 mg, and 20 mg, but you can enter any amount.
- Enter the listed price from the vendor’s product page.
- Add the shipping cost. Many vendors offer free shipping over a certain threshold; enter $0 if that applies.
The calculator instantly shows your total delivered cost and the per-milligram rate. Use the per-mg figure to compare the same peptide across different vendors or to decide whether a larger vial offers better value.
Tips for Comparing Peptide Prices
- Check the purity. A lower per-mg price is only a good deal if the vendor provides third-party certificates of analysis (COAs) confirming purity of 98 % or higher.
- Account for shipping tiers. Some vendors charge flat-rate shipping while others offer free shipping on orders above a minimum. Factor this in when buying single vials versus bundles.
- Watch for sales and bundle discounts. Many vendors run periodic promotions that can significantly reduce the effective per-mg cost.
- Compare the same dosage form. Lyophilized powder, pre-mixed solutions, and nasal sprays have different cost structures and shelf lives.
