Compounded Peptides ·
Compounded medications are prepared by licensed pharmacies operating under state and federal law; counterfeit medications are produced outside the legal system and typically misrepresent their identity, source, or composition. The distinction matters in the GLP-1 marketplace because both compounded and counterfeit products can arrive in nondescript vials, and consumers often struggle to tell them apart. FDA issued warnings throughout 2025 and 2026 about counterfeit semaglutide and tirzepatide shipped from overseas sources that copied Lilly or Novo Nordisk packaging elements. True compounded products come from a US-licensed pharmacy with a clearly printed label including the patient's name, the compounder's name, lot number, and beyond-use date.
