How long does it take to go from formula to finished product with a US manufacturer?

For a custom formula with a new manufacturing partner, expect 12 to 20 weeks from initial brief to first production run: 2 to 4 weeks for formulation and sampling, 2 to 4 weeks for stability initiation, 2 to 6 weeks for packaging procurement, and 4 to 6 weeks for production and QC. White-label or existing-formula projects can be significantly faster — sometimes 6 to 10 weeks total. AJ Cosmo Labs helps you track samples and milestones inside the app.
