TB-500 is not a controlled substance under the UK Misuse of Drugs Act 1971 and can legally be sold for in-vitro laboratory research. It is not licensed by the MHRA for human use. All products supplied by PeptX are strictly for in-vitro laboratory research and are NOT for human or animal consumption.
