Specialist Pharmacy

About us

The Specialist Pharmacy is the first compounding pharmacy in the UK, creating bespoke medicines designed to treat the symptoms of the menopause and other hormone-related conditions, as an alternative solution to the ‘one size fits all’ approach of standard HRT. We also provide a range of hormone-based treatments, vitamins and supplements designed to complement our compounding offer.

We believe in listening to the needs of prescribers and patients alike, to develop the best possible outcome for both. Our service is based on a unique combination of deep knowledge, the latest precision technology, exacting testing and customised delivery processes. We are registered, regulated and comply with the standards of the General Pharmaceutical Council (GPhC). Our rigorously trained pharmacists work only with suppliers operating in countries whose pharmaceutical raw materials and GMP standards are recognised by the EU.

Laboratory process


Specialist Pharmacy is regulated by the General Pharmaceutical Council, which has the responsibility of regulating all compounding pharmacies. This means that we prepare unlicensed medicine on a prescription-by-prescription basis.

Our ingredients are sourced from large, reputable pharmaceutical suppliers, all of which are compliant with Good Manufacturing Practice as recognised by the EU.

To compound medication, we mix a pre-prepared base with active ingredients (bio-identical hormones) in our laboratory.  Quality is of the highest importance to us.  We employ a computer-controlled process to reduce and eliminate error (each prescription is assigned a unique barcode) and use high precision equipment to ensure consistency.  Our Superintendent Pharmacist is responsible for ensuring that staff are well trained and that standard operating procedures are in place and followed.  She checks all prescriptions for safety and appropriateness as well as performing other quality checks.  Every medication can be traced back to its original formula, lab technician and ingredient source.
