What Should You Reconstitute Peptides With?
⚡ Direct Answer
Reconstitute research peptides with Bacteriostatic Water containing 0.9% benzyl alcohol (USP grade). The 0.9% benzyl alcohol preservative acts as a bacteriostatic agent that inhibits bacterial growth, allowing multi-dose vial use over 28 to 30 days when refrigerated. Sterile water without preservative lacks antibacterial action and should only be used for immediate single-dose applications.
