This peptide dosing calculator does the concentration math. Enter your vial size, bacteriostatic water volume and amount to see the volume to draw and the U-100 syringe units. It does not recommend a dose.
Enter every peptide in the vial and how many mg of each it contains — check the vial label.
The full volume you added to the vial. More water = lower concentration = bigger draw.
1 mg = 1,000 mcg. The other peptides in the blend come along in proportion — see the result table.
100 units = 1 mL. Enter how far you fill the syringe and see what each peptide works out to.

Important Disclaimer
This calculator is for educational purposes only. It does concentration arithmetic — it does not recommend a dose, and it cannot tell you whether a blend is appropriate. Always verify calculations with a healthcare provider. Peptide dosing should be supervised by a qualified medical professional. This tool does not constitute medical advice.
Blended vials combine peptides at a fixed ratio, so you can only set the dose for one of them — the rest follow in proportion. Several compounds commonly found in blends are not approved for human use in the United States. Concentration arithmetic is not a statement about safety, legality, or effective dose.
Total peptide content in the vial (e.g., 5 for a 5 mg BPC-157 vial)
1 mg = 1,000 mcg. Most peptides are dosed in mcg.

(Vial mg × 1,000) ÷ Water mL
Converts mg to mcg, then divides by the volume of water added to get mcg per mL.
Desired dose (mcg) ÷ Concentration
Divides your desired dose by the concentration to find how many mL to draw.
Volume (mL) × 100
A U-100 insulin syringe has 100 units per mL, so multiply volume by 100 to get units.
