## FAQ

### Why do peptide research results vary between researchers using the same compound?

Purity levels, reconstitution concentration, diluent type, and storage temperature all affect how a peptide behaves in solution. Without controlling and documenting these variables, no two experiments are truly comparable.

### Does diluent choice matter when reconstituting peptides?

Yes. Bacteriostatic water preserves a reconstituted solution longer than sterile water due to its benzyl alcohol content. Some peptides also dissolve better in acetic acid. pH and preservative content both affect stability and aggregation rate.

### How do storage conditions affect reconstituted peptide quality?

Reconstituted peptides degrade faster than dry lyophilized powder. Repeated warm-cool cycles and freeze-thaw events break down or aggregate peptide molecules. Consistent cold storage at 2-8°C gives the most stable working solution.
