Product Information
BAC Water 3ml is a sterile, bacteriostatic solution formulated with 0.9% benzyl alcohol to help prevent microbial growth during repeated use. This added protection allows for multiple withdrawals from the same vial, making it suitable for ongoing peptide protocols that require consistency over several uses.
The 3ml format provides a practical middle ground—offering more flexibility than smaller vials while avoiding the excess volume of larger ones. This makes it particularly useful for users who need a controlled amount of solution for reconstituting multiple peptides or maintaining dosing precision across a moderate timeframe.
It plays a key role in supporting the stability and usability of reconstituted peptides by reducing contamination risk and helping maintain solution quality. When stored properly, typically under refrigeration, it helps extend the usability of prepared compounds while ensuring reliable handling.

Common Questions
Frequently Asked Questions
How many peptide vials can I reconstitute with 3ml of BAC Water? +
If your protocol uses 1 mL per peptide vial, you can reconstitute up to three vials. At 1.5 mL per vial, two vials. At 3 mL per vial, one vial. The reconstitution calculator on each peptide product page will tell you exactly how much BAC water to add.
What is the benzyl alcohol concentration in BAC Water? +
All Peptides Costa Rica BAC Water contains 0.9% benzyl alcohol, which is the standard preservative concentration used in research-grade bacteriostatic water. This concentration is sufficient to inhibit bacterial growth while remaining compatible with peptide stability.
How should I store the 3ml BAC Water vial? +
Store sealed at room temperature or refrigerated (2–8 °C) before first use. After first opening, refrigerate at 2–8 °C and use within 28 days. Do not freeze after opening.
Can BAC Water affect peptide stability or potency? +
No, when used correctly, BAC Water does not affect peptide potency. The benzyl alcohol preservative is inert with respect to most peptide structures. Always verify solubility compatibility for your specific peptide, as some peptides (e.g. IGF-1LR3) may require dilute acetic acid or HCl for initial dissolution before diluting with BAC Water.
