Weight-loss injections sold online: warning signs to recognise

Information verified on 6 September 2026. The US approvals cited do not prejudge the status in Morocco. This information sheet is not a substitute for medical advice.

An attractive price, a photo of the packaging and a few testimonials are not enough to verify an injectable medicine. Before being persuaded, you must check the exact product, its authorisation and the professional responsible for dispensing it. The reassuring appearance of a website is no substitute for any of these elements.

Why the risk goes beyond mere counterfeiting

The FDA has reported problems with unauthorised versions of GLP-1: dosage errors, uncertain quality, misleading packaging and products sold under confusing names. A product may be risky even if the seller does not copy a well-known brand. Source: FDA alerts regarding unauthorised GLP-1s.

Retatrutide is a particularly good example of this issue. As of 6 September 2026, it remains experimental. Encouraging results from clinical trials do not transform the vials advertised online into authorised medicines. The manufacturer has also warned against their illegal sale. Source: alert from Lilly.

Seven warning signs that should make you stop the purchase

1. The promise of guaranteed results. Claims of precise, very rapid and ‘completely risk-free’ weight loss do not honestly describe a treatment.
2. No serious medical assessment. A few advertising messages are not enough to verify a product’s history, contraindications and associated treatments.
3. A professional identity that cannot be verified. It must be possible to verify the name of a doctor or a pharmacy independently of the seller’s account.
4. A ‘research only’ vial recommended for injection. A research reference does not constitute authorisation for human use.
5. Improvised mixing or conversion instructions. Asking the customer to calculate their own dose from an unlabelled product introduces a risk.
6. Guarantees are limited to a photograph or a certificate. A displayed document may be incomplete, relate to a different batch or be false.
7. Pressure to pay immediately. An offer that expires in a few minutes leaves little scope for independent verification.

What must be checked before any product is dispensed

This checklist reduces the risk of being misled, but it does not enable you to authenticate a medicine yourself. Some counterfeits are very good imitations of the original packaging. A parcel that arrives cold or bears a batch number is not, in itself, sufficient proof.

In Morocco, do not confuse foreign adverts with local access

An advert stating ‘FDA approved’ may refer to a different active ingredient or formulation from the product actually being sold. US approval does not prove that the bottle on offer is authorised, nor does it confirm that it is lawful to sell it in Morocco. It is essential to have the situation checked by a pharmacist and a doctor.

If you have already placed an order

Do not use a product you are unsure about just to ‘try a small dose’. Keep the packaging, receipt and any exchange slips, then seek advice from a pharmacist. If the product has been used, tell your doctor exactly what you have taken, even if the purchase seemed embarrassing: this information helps with your treatment.

Severe abdominal pain, persistent vomiting, significant discomfort or breathing difficulties require immediate medical attention. Do not wait for a response from the seller. This document does not provide any instructions on how to prepare or administer unauthorised products.
