A reliable webshop is transparent about who it is, what is in its products and what they do and do not do. Check, among other things, the Chamber of Commerce (KvK) number and address, a trust mark, the stated source, independent lab tests and that no medical promises are made.

Why this matters

The number of Dutch websites selling peptides is growing fast (Kassa). Some of them do not follow the rules. With these checks, you can quickly tell the difference.

8 checks before you order

  • Chamber of Commerce (KvK) number and business address are clearly shown on the site.
  • Trust mark such as Thuiswinkel Waarborg, with a working link to the certificate.
  • No medical promises. 'Heals injuries' or 'makes you lose weight' is not allowed for food or cosmetics.
  • No 'for research only' with consumer marketing. Anyone who labels a product 'for research only' but still sells it with sports photos and before-and-after images is getting around the rules.
  • No injection vials without a licence. Selling medicines online is only allowed with registration with the CIBG.
  • Source and composition are stated on every product, including origin (e.g. bovine or fish).
  • Independent lab tests or an anti-doping quality mark for supplements.
  • Secure payment methods such as iDEAL and a clear returns policy.

Red flags

Payment only via crypto or a bank transfer to another country, ordering via Telegram or other social media, and no customer service with a real address. The IGJ sees the trade increasingly shifting to social media (Hart van Nederland).

In short

A reliable webshop is transparent about who it is, what is in its products and what they do and do not do. If in doubt, do not order.
