🚨 A new California bill would impose $1,000-per-dose fines on unverified compounded GLP-1s, and bundles sourcing, testing, recordkeeping, and advertising rules into a single statute.
On May 18, 2026, the California State Assembly advanced AB 1990, the bill would create new requirements for certain compounded weight-loss drugs, including GLP-1 receptor agonists.
What AB 1990 would establish:
→ Sourcing standards requiring pharmaceutical-grade ingredients from FDA-registered, FDA-inspected manufacturers, with certificates of analysis on file
→ Quality-control testing before compounded GLP-1s are dispensed, with records retained for Board of Pharmacy review
→ Advertising disclosure rules, including FDA-approved active-ingredient risk information
→ Penalties of $1,000 per dose of illegally compounded drug, plus license revocation when applicable
The bill notably excludes licensed physicians and surgeons from its direct scope, targeting pharmacy-level compounders and the ingredient supply chain. Physicians remain subject to other applicable law.
AB 1990 sits inside a broader GLP-1 enforcement pattern. The FDA issued warning letters to 30 telehealth firms over compounded GLP-1 marketing in March 2026. Connecticut's Attorney General has settled cases tied to compounded GLP-1 advertising. California is now translating those concerns into statute.
California often sets the tone — other states tend to follow.
What Med Spa Owners should do now:
✔ Audit GLP-1 service pages and ads for claims that imply compounded equals FDA-approved
✔ Verify supplier files include sourcing, certificates of analysis, and testing documentation
✔ Maintain internal records of how compounded GLP-1 products are described and sourced
✔ Document the full prescribing and dispensing workflow
