TB-500 is a prescription substance in the United States. TB-500 / Thymosin Beta-4 is explicitly identified in FDA guidance as not suitable for 503A/503B compounding. Federal compliance risk for providers offering it is high. Patients should understand the legal status before use. In Florida, compounding is governed by the Florida Board of Pharmacy (FBP). In Florida, advanced practice registered nurses (APRNs) with prescriptive authority and physician assistants may prescribe compounded peptides within the scope of their collaborative agreement. Florida's telehealth laws permit prescribing without prior in-person visit in many contexts, which has made Florida a hub for telehealth peptide programs. Prescribers must hold a Florida license to prescribe to Florida patients.

Compounding Overview
Florida has a large and active compounding pharmacy sector. The Florida Board of Pharmacy (Department of Health) regulates sterile and non-sterile compounding, requiring separate permits for each type. Florida pharmacies that compound sterile preparations must comply with USP 797 and undergo periodic inspections. Florida has specific rules for "office use" compounding — a provision that allows prescribers to order pre-mixed sterile compounds for use in their offices, which is relevant to many peptide clinics.
