BAC water guide and calculator

Reconstitution guides for laboratory use. Vial amount, water volume, concentration, and measured draw volume.

BAC water guide

Work through the label, water volume, concentration, and recordkeeping steps before using the calculator.

Start with the labelled peptide amount in milligrams. Convert milligrams to micrograms by multiplying by 1,000.

Example: 10 mg equals 10,000 mcg before any water is added.

The amount of BAC water sets the concentration. More water lowers the concentration per mL.

Example: 10 mg mixed with 2 mL gives 5 mg/mL, or 5,000 mcg/mL.

Divide the target amount by the concentration in mcg per mL.

On a 100 unit syringe, 1 mL equals 100 units.

Add the BAC water to the peptide vial, then gently mix by swirling or rolling. Do not shake.

Use a new sterile syringe and needle for each vial. Do not reuse syringes.

Peptides that have not been reconstituted with bacteriostatic water should be stored refrigerated until ready for use.

Once reconstituted with bacteriostatic or sterile water:

Enter your vial content, the volume of BAC water added, and your target amount per injection to work out concentration and draw volume.

Numbers only — this tool performs unit conversions and does not suggest amounts.

Unit conversion only — not a dosing guide.

For research purposes only. Results are mathematical conversions and should not be interpreted as dosing instructions.

These formulas explain the calculator output. They are arithmetic references for laboratory records, not dosing instructions.

mcg per mL = peptide mg x 1,000 / BAC water mL

mcg per unit = mcg per mL / 100

draw mL = target mcg / mcg per mL
