The peptide chains remain intact
If a '50mg' vial actually contains 53mg and you add 2mL bacteriostatic water, your true concentration is 53 2 = 26.5mg/mL
Best choice for 15 mg vials: 3 mL creates a clean 5 mg/mL concentration
However, for any study involving oral administration, long-term protocols, or situations where temperature control might be inconsistent, the extra investment in the arginate salt is, in our professional opinion, well worth it
Why Many Laboratories Prefer Bacteriostatic Water Most peptide laboratories choose bacteriostatic water because it offers: Simplicity Sterility Reduced contamination risk Better usability for repeated handling It is generally considered the standard option for routine peptide reconstitution
Monitor for potential side effects including injection site pain or allergic reactions
