Overview & background
A quick PepsVN reference for vial sizes, concentration math and links to each product page.
Use the calculator to work out concentration and syringe units for any vial, or find your product in the cards below.
Enter the vial size and the liquid added in the calculator, or find your product below. Each card shows the concentration at two common volumes.
Peptide reconstitution calculator
Enter the vial size, the BAC water added and your research amount. The calculator shows the syringe units and mL to draw, the concentration, and how many amounts the vial holds.
Draw to
5 units
0.05 mL on a U-100 syringe
Same amount, different BAC water
More water means more units for the same amount, which makes small amounts easier to measure.
| BAC water | Concentration | Units | mL |
|---|
Units = mL × 100 on a U-100 syringe. The calculator assumes the full labelled amount is in the vial; the batch certificate shows the measured quantity. For laboratory research calculations only.
Find your peptide faster
Each card shows the concentration for one vial size at two common volumes. Use the calculator above for any other amount.

What changes when you add more liquid?
Adding more liquid does not change the total peptide in the vial. It only lowers the concentration. These examples use a 10 mg vial.
2 mL → 5 mg/mL
Less liquid gives a stronger solution: 5,000 µg in every mL.
3 mL → 3.33 mg/mL
A middle option. Check how much the vial holds before adding more liquid.
4 mL → 2.5 mg/mL
More liquid gives a weaker solution. Large vials such as NAD+ or Glutathione are often made up with more liquid for this reason.
Peptide reconstitution questions people search for
How much BAC water should I add to a peptide vial?
There is no single correct amount. The liquid changes the concentration, not the amount of peptide. Many people choose a volume that gives a round number, such as 5mg/mL for a 10mg vial in 2mL. Many small peptide vials work well with 2mL or 3mL. Larger vials such as NAD+ or Glutathione often make more sense with 3mL or 4mL.
Does adding more BAC water make the peptide weaker?
It makes the liquid less concentrated, but it does not reduce the total amount of peptide in the vial. A 10mg vial still contains 10mg whether you add 1mL, 2mL, or 3mL.
What is the easiest concentration for peptide calculations?
Easy math depends on the vial. For a 10mg vial, 2mL gives 5mg/mL and 4mL gives 2.5mg/mL. Round numbers like these keep later calculations simple.
Can I use the cards instead of the calculator?
The cards cover each vial size we stock at two common volumes. Use the calculator at the top of this page for any other volume.
Do peptide powders need cold shipping in Vietnam?
Lyophilized peptide powder is generally highly stable during normal short-term shipping and can tolerate warm domestic transit much better than reconstituted liquid. Reconstituted peptides should be refrigerated.
Why do some peptide pages use different BAC water amounts?
Because vial sizes differ a lot. A 5mg vial, 50mg vial, 500mg vial, and IU-based vial should not all use the same example.
