The Medicines and Healthcare products Regulatory Agency (MHRA) has refreshed its guidance on how research-only peptides should be presented to buyers. The headline change: the "not for human consumption" statement must now appear on the primary container label itself, not only on an accompanying certificate of analysis.
Why it matters
For researchers, the practical effect is small — the legal status of these compounds in the UK is unchanged. But for vendors, the labelling requirement raises the bar on compliance and makes it easier to distinguish legitimate research suppliers from those marketing for human use.
What to watch
Expect reputable vendors to update packaging over the coming weeks. We will track which suppliers comply and reflect it in our vendor reviews.
