A custom peptide face mist typically takes 12–20 weeks from brief to bulk production. This includes formulation (4–6 weeks), prototype sampling (2–3 weeks), accelerated stability testing at 45°C/75% RH (8–12 weeks), and regulatory review. Semi-custom routes using a modified base formula can cut lead time to 6–10 weeks. Use the AJ Cosmo Labs app to track each milestone.
