Peptide Reconstitution & Injection Calculator
Enter your vial amount, diluent volume, and target dose to estimate concentration, mL per injection, and insulin syringe units.
What this peptides dosage calculator does
This calculator helps you convert reconstitution inputs into practical injection measurements. If you know how many milligrams are in your vial and how much liquid you added, the calculator estimates concentration and translates your target microgram dose into:
- Concentration in mcg per mL
- Volume per dose in mL
- Equivalent syringe units on an insulin syringe scale
- Estimated number of doses per vial
Core dosage formulas
Total peptide (mcg) = vial mg × 1000
Concentration (mcg/mL) = total peptide mcg ÷ diluent mL
mL per injection = desired mcg ÷ concentration mcg/mL
Syringe units per injection = mL per injection × syringe units per mL
Total injections = total peptide mcg ÷ desired mcg
Step-by-step example
Example inputs
- Vial: 10 mg
- Diluent: 2 mL
- Target dose: 250 mcg
- Syringe scale: U-100 (100 units = 1 mL)
Result breakdown
10 mg = 10,000 mcg total peptide. Divide by 2 mL to get 5,000 mcg/mL concentration. A 250 mcg dose then requires 0.05 mL. On a U-100 syringe, 0.05 mL equals 5 units.
This means each injection is approximately 5 units, and the vial provides around 40 injections at this dose level.
Practical tips to avoid dosing mistakes
- Keep units consistent: mg and mcg are not interchangeable. 1 mg = 1000 mcg.
- Write your mix ratio: Label the vial with date and concentration.
- Confirm syringe scale: U-100 and other scales are different.
- Avoid guessing: Always calculate before drawing a dose.
- Use sterile technique: Improper handling increases contamination risk.
Frequently asked questions
Why does changing mL of diluent change syringe units?
Adding more diluent lowers concentration, so you need a larger volume to reach the same microgram dose. That larger volume converts to more syringe units.
Can I use this as a peptide reconstitution calculator?
Yes. The calculator effectively performs peptide reconstitution math by converting vial strength and diluent volume into usable dose measurements.
Does this tell me what dose I should take?
No. It only calculates dose volume from values you enter. It does not recommend treatment, frequency, or safety for any specific compound.
Final note
Accurate math is essential whenever concentration and injection volume are involved. Use this peptides dosage calculator to reduce manual calculation errors, but pair it with professional medical guidance, proper product verification, and strict sterile handling practices.
