A precision calculator for laboratory peptide reconstitution. Enter your vial details and target research dose — we’ll show you exactly where to fill the syringe.
— Step 01
Vial & dose details
01 —Enter vial strength & water volume
02 —Set your target dose in mcg or mg
03 —Read the syringe draw value

Volume to draw
Draw to this mark
25units
On a 0.5 ml (50-unit) insulin syringe — fill to the 25-unit line.
Calculated draw exceeds the selected syringe capacity. Use a larger syringe or split the dose across multiple draws.

For laboratory research use only. This calculator is provided as a convenience for qualified researchers conducting in-vitro work. Always verify calculations independently and consult appropriate technical documentation.
Calculations are based on the formula: (target dose × reconstitution volume) ÷ vial mg = volume to draw. Insulin syringe units assume 100 units = 1 ml.
Common Questions
Need a hand?
Does this work for any lyophilised peptide?
Yes — the maths is the same for any vial. What changes is your chosen reconstitution volume and target dose. As long as you know the mg in the vial and how much bacteriostatic water you’ve added, the calculator will work.
Tip: stick to one reconstitution style for a product so your results stay consistent across draws.
Why do my results change when I use 1ml vs 2ml of bac water?
More water means a more diluted solution, so the volume you’ll need to draw for the same target dose increases. The calculator updates automatically when you change the reconstitution volume — useful for testing different concentrations before committing.
What’s the difference between mcg and mg?
1 mg = 1,000 mcg. Most peptide research doses are quoted in micrograms (mcg) because the amounts are small. Use the toggle next to the dose input to switch between units — the result updates instantly.
What should I do if my calculated draw exceeds the syringe size?
The calculator will show a warning and the fluid in the visual will turn red. You have two options: switch to a larger syringe size using the buttons above, or split the dose across multiple draws. Reconstituting with more water also reduces the draw volume.
Is this calculator suitable for human use?
No. All products supplied by Bangkok Peptides are sold strictly for in-vitro laboratory research purposes only. This calculator is a reference tool for qualified researchers conducting in-vitro work. It is not intended to support human or veterinary use.
How accurate is this calculator?
The maths is precise to the values you enter. Real-world accuracy depends on the precision of your reconstitution (how exactly you measure the bac water) and your syringe — insulin syringes typically have a tolerance of ±5%. Always verify calculations independently.
