How to Store Reconstituted Peptides: Fridge, Freezer, Time
Do peptides need refrigeration once reconstituted? Why solutions degrade faster than powder, how long they keep, time out of the fridge and freezing aliquots.

Bacteriostatic Water for Peptides: When and How to Use It
When bacteriostatic water suits peptide reconstitution, which peptides need caution with benzyl alcohol, how to choose the volume, and what the evidence shows.
Lab Handling
What Is Bacteriostatic Water? Composition and Lab Use
Bacteriostatic water is sterile water for injection with 0.9% benzyl alcohol. What it contains, how the preservative works, label restrictions and its lab uses.
Lab Handling
Bacteriostatic Water vs Saline and Reconstitution Solution
Is 'reconstitution solution' the same as bacteriostatic water? How bac water compares with bacteriostatic saline, sterile water and acetic acid.
Lab Handling
Bacteriostatic Water vs Sterile Water: Lab Differences
Bacteriostatic water has 0.9% benzyl alcohol and multi-dose vials; sterile water has no preservative and is single-use. Which suits peptide work.
Lab Handling
Does Bacteriostatic Water Need to Be Refrigerated?
Unopened bacteriostatic water is labelled for room temperature (20–25 °C). What changes after opening, how long a vial lasts, and when it should be discarded.
