503A plus 503B versus 503A patient-specific only.
AnazaoHealth and Empower Pharmacy share a 503A compounding foundation, but Anazao extends into 503B office-use bulk supply, pain management sterile prep, and nuclear medicine through myAnazao. If your clinic prescribes only patient-specific GLP-1, hormone, and peptide compounds, either compounder fits. If you also stock office-use bulk vials or need specialty sterile prep, AnazaoHealth's broader scope adds those channels without a second vendor relationship.
The decision is about supply channel and specialty depth, not just formulary overlap. Empower is purpose-built for high-volume 503A patient-specific ordering through LifeFile. AnazaoHealth spans both 503A and 503B in one portal, which may reduce vendor count if your clinic mixes patient-specific and in-office supply.
