Regulation & market
503A pharmacy
A traditional compounding pharmacy, compounding for individually identified patients against a prescription.
In plain terms
503A facilities are overseen primarily by state boards of pharmacy and are exempt from certain federal requirements — including the requirement to follow GMP — on the condition that they compound patient-specific preparations rather than manufacture at scale.
Guides that use this term
BPC-157, TB-500, CJC-1295 and ipamorelin: what the FDA has actually published about each, why “removed from Category 2” does not mean cleared, and what is still unlawful to compound.
The shortages ended, and with them the enforcement discretion that allowed mass compounding of semaglutide and tirzepatide. What FDA actually said, with the dates, and what remains permitted.
