the working
- BPC-157: 10 mg ÷ 2 mL = 5 mg/mL
- 0.25 mg ÷ 5 mg/mL = 0.05 mL = 5 units
- TB-500: 5 mg/mL × 0.05 mL = 0.25 mg
If this is a prescription, the dose and volume on your pharmacy label take priority. Ask your pharmacist about any mismatch.

the arithmetic
formulas
- concentration = amount in the vial ÷ water added (mg/mL)
- mL per draw = amount per draw ÷ concentration
- syringe units = mL × 100 (U-100) or × 40 (U-40)
- water to add = vial amount × units ÷ (amount per draw × 100)
- cost per draw = vial price × amount per draw ÷ vial amount
Worked: 10 mg ÷ 2 mL = 5 mg/mL; 0.25 mg ÷ 5 = 0.05 mL; × 100 = 5 units.
what the numbers mean · where they come from
terms and sources
- Label amount or measured amount. The calculator starts from the amount printed on the vial. A lot certificate’s measured content (net peptide content, in mg) can replace it for the vial that was tested. HPLC purity is a share of peak area, not a mass, so a purity-only correction is shown as an estimate. See HPLC, certificate of analysis and how to read a peptide COA.
- Concentration. Amount in the vial ÷ water added. Terms: reconstitution, bacteriostatic water, lyophilized.
- Syringe units. A volume: 0.01 mL per unit on a U-100 syringe, 0.025 mL on U-40. Units say nothing about the compound until the concentration is known.
- Cost per draw. Vial price × amount per draw ÷ vial amount, from the price per mg of a current offer. Price history: peptide price tracker.
Arithmetic only, on the numbers entered. Amounts from labels or trials are cited references, not recommendations; PeptideTech does not give personal use instructions and does not test products.
