What type of water should I use to reconstitute peptides?

Bacteriostatic Water (BAC water) is the standard choice for reconstituting research peptides. It contains 0.9% benzyl alcohol which prevents bacterial growth and allows the reconstituted peptide to be stored for longer periods when refrigerated.

How long can I store a reconstituted peptide vial?

Most reconstituted peptides stored in bacteriostatic water and refrigerated at 36-46°F remain stable for 28-30 days. Always check pharmacy or vendor guidance specific to your peptide, as some degrade faster than others.

What app should I use to track my peptide reconstitution and dosing?

Shotlee includes a built-in peptide reconstitution calculator and dose tracker. You can log vials, track remaining doses, and keep a full record of your peptide research protocol in one place.

Safety, Sterility & Precision

Proper reconstitution is the most critical step in research. Using Bacteriostatic Water correctly and maintaining sterility ensures the integrity of your Tirzepatide, Retatrutide, or other peptides.

The 5-Step Prep Process

Sanitize Everything: Use 70% isopropyl alcohol pads on the tops of both the peptide vial and the BAC water vial.

Draw BAC Water: Use a sterile syringe to draw the exact amount of Bacteriostatic Water needed for your ratio.

The Slow Drip: Inject the water into the peptide vial at an angle, letting it run down the glass wall. Never spray directly onto the powder.

Gently Swirl: Do not shake. Gently swirl the vial until the solution is clear. Some peptides (like BPC-157) dissolve instantly; others may take minutes.

Storage: Once mixed, most peptides must be refrigerated to prevent degradation.
