Buying & prescription

Recognising counterfeits

Counterfeit GLP-1 pens and illegal sellers are a real danger: you don't know what's in it, how it was stored or whether it is safe. The clearest warning signs are no prescription or intake, a strikingly low price and a foreign web shop. The safe route always runs via a recognised clinic or doctor and a pharmacy.

Why counterfeits are dangerous

Counterfeit pens may contain an incorrect dosage, other substances or no active substance at all. In addition, any form of control and guidance is missing. Possible consequences:

  • incorrect or dangerous dosage;
  • contaminants or unknown ingredients;
  • no monitoring of side effects or contraindications;
  • improper storage, making the medicine no longer reliable.

Signs of illegal supply

Watch out for these red flags:

  • No prescription or intake requested — with legal supply, a doctor always assesses your suitability;
  • Too cheap or striking discounts and 'offers';
  • Foreign web shop or unclear seller without verifiable details;
  • payment via unusual methods;
  • packaging or package leaflet in a foreign language or without Dutch information.
Just one of these signs is already reason to refrain from the purchase. GLP-1 medication is prescription-only; see buying without a prescription.

The safe route

Always choose a recognised clinic or doctor that carries out an intake, and a pharmacy that supplies the medication. That way you can be sure the product is genuine and controlled and that guidance comes with it. Want to compare providers? Take a look at the clinics.
