Is TB-500 Legal in the UK and UAE?
TB-500 (thymosin beta-4 fragment) is not a controlled substance in the UK. It has no MHRA marketing authorisation, so it can only be lawfully sold and supplied as a research reagent, not for human use.
TB-500 is not scheduled as a controlled substance in the UAE and can be lawfully supplied as a research-use-only compound; it holds no MOHAP/DHA authorisation for clinical use.
UK detail
Like BPC-157, TB-500 sits outside the Misuse of Drugs Act and Psychoactive Substances Act schedules, so possessing it for genuine research is not itself a criminal matter. It has never held a UK marketing authorisation, so any supply framed around human injection, dosing, or recovery outcomes would breach the Human Medicines Regulations 2012 — which is why compliant UK suppliers restrict listings to identity, purity, and handling information rather than use guidance.
UAE detail
TB-500 is not on the UAE controlled-substance list. It reaches the market only through the research-reagent channel unless dispensed under DHA/MOHAP clinical supervision using pharmaceutical-grade stock, which is a separate and much narrower route than online research-peptide suppliers operate through.
This is a general overview, not legal advice, and law in this area can change. For a specific situation, consult a solicitor with life-sciences regulatory experience (UK) or MOHAP/DHA directly (UAE).
