Is an online service selling weight loss injections or prescription medication without a GP safe?
No. Prescription medication sold without a valid prescription is illegal and potentially dangerous.
Last reviewed: 1 June 2026
Explanation
The popularity of GLP-1 weight loss medications has created a large grey market of online sellers offering prescription drugs without a valid prescription or medical assessment. These sites either sell counterfeit products of unknown composition, genuine products sourced illegally, or conduct a cursory online questionnaire that does not meet the standard of a real medical consultation. The risks include receiving a product of unknown safety, missing contraindications that a doctor would have identified, and having no medical support if you experience side effects. In the UK, all online pharmacies must be registered with the GPhC and display the EU Common Logo. In the US, prescription drugs must be dispensed by a licensed pharmacy following a valid prescription from a licensed prescriber.
Common red flags
- No prescription or only a very basic online questionnaire required
- Pharmacy cannot be verified on the GPhC register (UK) or state pharmacy board (US)
- Price is dramatically lower than regulated online pharmacies charge
- Products are shipped from overseas without declared manufacturer details
What to do now
- Only obtain prescription medication through a registered pharmacy following a valid prescription
- In the UK, verify the pharmacy at pharmacyregulation.org and look for the EU Common Logo
- Report illegal online pharmacies to the MHRA (UK) or FDA (US)
- Consult your GP or a registered specialist for a proper assessment
Frequently asked questions
Are all online pharmacies unsafe?
