Who runs Hey Slim.
Three records sit behind every online pharmacy: the company, the registered pharmacy and the brand you see. For Hey Slim, here is each one. The brand name and the registered pharmacy name differ. Many online services dispense through a separate registered pharmacy, and the law allows this.

Before you order from Hey Slim.
- Check the register yourself. Open the GPhC entry and match the number to the one on the website.
- Expect a real consultation. A prescriber reviews every order before anything is dispensed. Walk away from any site skipping this step.
- Check the full price. Some providers include the consultation and delivery. Others add both at checkout.
- Check delivery. Most use Royal Mail Tracked 24 or DPD, with cold-chain packing for injections. Delivery guide →
- Treat discount codes with care. A code never makes a pharmacy legitimate. Registration does.
