Begin by selecting the amount of peptide you plan to inject per dose. This step is essential because it determines the exact volume of the final solution needed for each injection. Enter your desired dose in milligrams (mg).
Using the Bacteriostatic Water Calculator, the system will automatically determine how much of the reconstituted peptide solution you need to draw per injection. This ensures your dosing is precise and consistent every time.


For small, daily doses requiring frequent injections, 1 mL or less of bacteriostatic water is usually sufficient, allowing for accurate micro-dosing.
For most standard peptide protocols (around 20 doses per vial), 2 to 3 mL of bacteriostatic water is commonly used. This dilution works well for:
For GLP-1 peptides like Semaglutide and Tirzepatide, which are highly potent and used in very small amounts, 0.5 to 1 mL of bacteriostatic water is typically enough for proper dilution.
When reconstituting peptides, both under-dilution and over-dilution can cause issues. Understanding these risks helps ensure safe and accurate dosing.
