Script Unlock connects California patients with verified 503A and 503B compounding pharmacies, both resident and non-resident. With 39.5M residents and 7% uninsured, California's compounding demand is among the highest in the country.

How to Verify a California Compounding Pharmacy
- 1Look up the pharmacy on the California Board of Pharmacy website — confirm active license and good standing
- 2Confirm 503A or 503B registration — both are legal but follow different rules; sterile injectables require 503A patient-specific or 503B outsourcing licensure
- 3Ask for a Certificate of Analysis (CoA) for your specific API — pharmaceutical grade only, from a verified supplier
- 4Verify USP 795 (non-sterile) and/or USP 797 (sterile) compliance — modern compounders test and document this
- 5Confirm valid patient-specific prescription is required — any pharmacy selling without one is illegal and unsafe
Valid prescription required for all compounded medications. Only use California-licensed (resident) or California-non-resident-permitted compounders verified by the state pharmacy board.

FAQs — Compounding Pharmacies in California
How do I find a compounding pharmacy in California?
Script Unlock lists verified California-licensed compounding pharmacies — both resident and out-of-state pharmacies with valid California non-resident permits. You can browse by drug, by city, or submit a prescription and have local compounders bid.
What is the difference between a 503A and 503B compounding pharmacy in California?
503A pharmacies compound on a patient-specific prescription basis (your name on every preparation). 503B pharmacies are FDA-registered outsourcing facilities that prepare larger batches for clinics. Both can serve California patients; 503B is more common for provider-administered injectables, while 503A handles individual prescriptions.
Are compounded medications safe in California?
Yes — when prepared by a state-licensed compounder following USP 795 (non-sterile) and USP 797 (sterile) standards using pharmaceutical-grade APIs. Script Unlock verifies state-board licensure before listing. Avoid any pharmacy that won’t share Certificates of Analysis or that sells without a prescription.
Does insurance cover compounded medications in California?
Usually no — most California insurance plans exclude compounded medications. Cash pay is standard. The good news: compounded drugs frequently cost less than insurance copays on brand equivalents, especially for HRT and GLP-1 therapy.
Can a California compounding pharmacy compound any drug?
Almost — with key exceptions. They cannot compound copies of commercially available drugs in the same strength (with limited shortage exceptions), they cannot use unapproved active ingredients, and they must follow the FDA bulks list for active substances. Within those limits, California compounders cover HRT, GLP-1, pediatrics, pain, vet, sterile injectables and more.
