## FAQ

### Does shaking a peptide vial ruin it?

Vigorous shaking forces air into the solution, and peptides can unfold and clump at the air-water surface. Gentle swirling dissolves the powder without that risk.

### Should you use glass cartridges instead of plastic for storage?

Peptides can stick to plastic surfaces over time, slowly lowering the usable concentration. Neither glass nor plastic is perfectly inert: glass flakes due to chemical delamination have been observed in parenteral liquid formulations after long-term storage (Jiang et al. 2013), the unpredictable nature of peptide binding to surfaces requires optimization of experimental containers (Goebel-Stengel et al. 2011), and cetrorelix adsorbed more to glass than to polypropylene (Grohganz et al. 2004).

### How long does bacteriostatic water stay effective after reconstitution?

The benzyl alcohol preservative in bacteriostatic water is generally treated as effective for about a month under refrigeration, but that timeframe covers bacterial control, not the peptide's own stability.
