Peptide Reconstitution & Dose Calculator
Use this tool to estimate concentration, syringe units per dose, and vial duration after mixing a peptide vial.
What is a particle peptides calculator?
A particle peptides calculator helps you convert vial strength and liquid volume into practical dosing numbers. Instead of guessing, you can quickly answer:
- How strong is my solution in mcg per mL?
- How many syringe units equal my target dose?
- How many total doses are in one vial?
- How long will the vial last at my planned frequency?
How the calculator works
1) Convert mg to mcg
Peptide vials are usually labeled in milligrams (mg), but dosing plans are often written in micrograms (mcg).
total mcg = vial mg × 1,000
2) Find concentration after mixing
Once diluent is added, concentration depends on total mcg and total mL.
mcg/mL = total mcg ÷ diluent mL
3) Convert concentration to syringe units
Most insulin syringes use 100 units per 1 mL, but you can change this value above.
mcg per unit = (mcg/mL) ÷ syringe units per mL
units needed = target mcg ÷ mcg per unit
Example walkthrough
Suppose you have:
- 10 mg vial
- 2 mL diluent
- 250 mcg target dose
- 100-unit syringe
You get a concentration of 5,000 mcg/mL. Each syringe unit equals 50 mcg, so a 250 mcg dose is 5 units.
Common mistakes this tool helps avoid
- Confusing mg and mcg (off by 1,000x).
- Forgetting to account for total mixed volume.
- Assuming all syringes use the same unit scale.
- Estimating doses without checking vial duration.
Important safety note
This calculator is for educational and planning use only. It does not replace professional medical advice, clinical judgment, or product-specific instructions. Always verify calculations independently and consult a licensed clinician or pharmacist for medical use.
Quick reference tips
- If you increase diluent volume, the solution gets less concentrated.
- If target dose increases, required units increase proportionally.
- Rounding to the nearest 0.5 syringe unit can make measurement easier.
- Keep records of batch strength and date mixed.
