Peptide Reconstitution
Calculator
Calculate exactly how much solvent you need and how many units to draw per dose. Select a peptide below or enter your own values. For laboratory research use only.
Quick-select by peptide

Peptide amount in vial
As printed on the vial — e.g. 5 mg or 10 mg
Reconstitution solvent (BAC water)
More water = lower concentration per ml, easier to measure accurately
Target sample quantity
In micrograms (mcg) — 1 mg = 1000 mcg
Measurement vessel capacity
Select the volume capacity of your graduated measurement vessel — U-100 scale (100 units = 1 ml)

How it's calculated
What is BAC water?
Bacteriostatic water (BAC) contains 0.9% benzyl alcohol as a preservative, allowing multiple draws from the same vial while inhibiting microbial growth.
U-100 graduated vessel
A U-100 graduated vessel has 100 units per ml — if you need 0.25 ml, measure to the 25-unit mark. The 0.5 ml / 50U format is standard for small-volume sampling.
Storage after reconstitution
Store reconstituted peptides refrigerated (2–8°C), protected from light. Use within 28 days. Keep unreconstituted vials in the freezer.
