Regulation

Is methylene blue legal in Europe? An honest, source-backed answer: there is an EMA-approved methylthioninium medicine for one narrow use, while research-grade methylene blue is a lab reagent (RUO) — not an approved supplement or nootropic.

Is Semax legal in Europe? It is approved as a drug in Russia but holds no EMA authorisation, so in the EU it is a research reagent only. An honest, source-cited look at what ‘legal’ really means here.

Selank is registered as a drug in Russia but has never been approved as a medicine in the EU. The honest legal answer depends entirely on what you intend to do with it.

Is PT-141 (bremelanotide) legal in Europe? It is FDA-approved as Vyleesi in the US, but holds no EMA authorisation and never even completed an EU application, so in Europe it is a research reagent only. An honest, source-cited look at what ‘legal’ really means here.

Is Tesamorelin legal in Europe? It was never authorised by the EMA — an application was withdrawn in 2012 — so in the EU it is a research reagent only. An honest, source-cited look at what ‘legal’ really means, including its WADA status.

Is Epitalon legal in Europe? It has no EMA authorisation and is not approved anywhere in the world as a marketed medicine, so in the EU it is a research reagent only. An honest, source-cited look at what ‘legal’ really means here.

Is NMN legal in Europe? It is classified as a Novel Food — and as of 2026 still unauthorised, with EFSA opinions in and applications pending. The honest, source-cited answer for researchers.

The 2026 list names dozens of growth-hormone peptides as prohibited at all times for athletes. But the silences in Section S2 — BPC-157, TB-500, MOTS-c — matter as much as the named substances.

RUO is a labelling category about intended use, not a quality grade or a safety claim. It is legitimate for genuine laboratory science — and routinely abused by the grey market as a fig leaf. Here is what the label actually does, and what it cannot.

A research peptide sold across Europe, never approved as a medicine, and quietly governed by the question almost nobody asks correctly.
