Peptide Calculator
What is bac water?
Bacteriostatic water (bac water) is sterile water with 0.9% benzyl alcohol, used to safely mix peptides and prevent contamination.
How do I calculate my dosage?
Fill in the vial size, bac water amount, and desired dose, then click the calculate button to get precise results.
Can I store mixed peptides?
Yes, mixed peptides should be stored in the refrigerator and used within the recommended time frame as stated by the manufacturer.
Why does my injection volume seem low?
The injection volume depends on the desired dose and concentration. If it seems low, double-check your inputs.
