Ex-Drug Dealer Sells Unlicensed Weight Loss Jabs
6 Jun
Summary
- A convicted drug dealer is now selling unapproved weight loss injections online.
- He prepares and promotes syringes with explicit instructions for users.
- Health experts warn of a public health crisis from such illegal sales.

Mark Allen, 46, who was previously jailed for two-and-a-half years for drug dealing, is now selling unlicensed weight loss injections online. He promotes peptides such as Retatrutide on social media platforms like TikTok and Instagram, where he also shares preparation instructions and success stories.
Allen claims the substances are "not for human consumption," a common tactic to circumvent UK law. However, his online content clearly markets them for weight transformation and other health benefits. Retatrutide is an experimental drug not approved for use in the UK and is illegal to market for human consumption under current regulations.
Health experts are raising alarm bells about the growing trend of unregulated peptide sales online. They warn that this practice, often disguised as research chemical sales, poses significant health risks and could lead to a widespread public health crisis if not addressed decisively by the government.
