Is TB-500 legal in Netherlands?

TB-500 is among the peptides readers most often ask about in Netherlands. This page focuses on the regulatory reality there, not on how to obtain or use it, because that is where reliable, localized information is hardest to find.

In Netherlands, TB-500 has no marketing authorisation and is not an approved medicine anywhere in the world. It circulates online as a “research chemical” or “not for human use” product. That label does not make human use lawful or safe.

Importing TB-500 into Netherlands, including for personal use, is restricted, because it is an unauthorised medicine; customs may detain shipments. A “for research use only” label does not legalise import for human use. Personal possession of TB-500 in Netherlands sits in a grey area: it is not a scheduled controlled substance, so simple possession is generally not a drug-scheduling offence, but it is an unauthorised medicine and enforcement targets sale and supply.

TB-500 is named on the WADA Prohibited List as a growth-hormone secretagogue (section S2), so it is banned in sport at all times for competing athletes. That is an independent reason for caution regardless of local medicines law.

Selling or supplying TB-500 without the required authorisation is an offence in Netherlands. CBG-MEB (Medicines Evaluation Board) / IGJ (Health and Youth Care Inspectorate) sets out the applicable sanctions; we do not reproduce specific figures here because they change.
