## FAQ

### Why should I not shake a peptide vial after adding water?

Shaking introduces air and mechanical force that physically tear the delicate protein chains, creating foam which is destroyed protein, and rendering the sample useless for accurate research.

### What is the difference between bacteriostatic water and sterile water for peptides?

Bacteriostatic water contains 0.9% benzyl alcohol to stop bacteria growth for multi-use vials, while sterile water has no preservative and is used for single-use vials or peptides that the alcohol would destroy.

### How long does a reconstituted peptide last in the fridge?

A typical peptide in a fridge at 4 degrees Celsius will last for one to two weeks before significant degradation occurs, but the exact time depends on the specific peptide's stability and the diluent used.
