Masters Head Office

Masters began in 1984 in the UK, founded by Dr Zulf Masters. Building strong partnerships with pharmaceutical manufacturers, Masters was able to supply quality products to countries that had limited or no access to such medicines. 35 years later, these partnerships have grown and the business has evolved.

London, UK


Our head office is based just outside of London, where we have been located since 1984. Here our business has grown from only a handful of employees, to now having over 50 experienced and dedicated staff. Our UK office is also our central hub for Finance, Operations, Global QA, Global PV, Sales, Marketing, and Distribution. Our MHRA and Home Office regulated warehouse operating to EU GDP standards handles products for shipment to different parts of the world.


We are also the exclusive distributor of Siklos in the UK, working with the NHS and hospitals, across the country. For more information about Siklos, please click on the links below.
