## FAQ

### Why do longer peptides stick to container walls more?

Longer peptides have more amino acids and more surface area, giving them more contact points to adhere to plastic or glass surfaces through hydrophobic and electrostatic interactions.

### Are borosilicate glass cartridges better than plastic for peptide storage?

Yes. 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 can I reduce peptide loss during reconstitution?

Minimize transfer steps between containers, use low-bind or glass vials, add diluent directly to the peptide vial, and avoid repeated freeze-thaw cycles that increase surface exposure.
