CALCULATE PERFECT DOSES

Bacteriostatic water is sterile water containing a small amount of benzyl alcohol, which inhibits bacterial growth. It is used to reconstitute lyophilized (freeze-dried) peptides because it allows a vial to be safely accessed multiple times over its usable life, unlike plain sterile water.

One milligram (mg) equals 1,000 micrograms (mcg). To convert mg to mcg, multiply by 1,000; to convert mcg back to mg, divide by 1,000. This calculator handles that conversion for you automatically when it computes total peptide content from your selected vial size.

Standard insulin syringes are marked in units rather than milliliters, with 100 units equal to 1 mL. Because these markings are far easier to read precisely at small volumes than mL graduations, converting your injection volume into units allows for much more accurate, repeatable dosing.

If the calculated units exceed your selected syringe's capacity, the calculator flags it with a warning. In that case, consider using a larger syringe, adding more bacteriostatic water to reduce concentration, or splitting the dose across two separate draws.

Most reconstituted peptides remain stable for approximately 2 to 4 weeks when refrigerated at 2 to 8 degrees Celsius and protected from light. Exact stability varies by compound, so always refer to the specific handling guidance for your peptide.

Yes. The underlying reconstitution math is universal and applies to any lyophilized peptide, since it is based only on vial mass, dilution volume, and desired dose. This tool is intended strictly for research and educational reference, not for determining human or animal dosing.
