Platform Moderation and Safety Actions

A spokesperson for the messaging service said it actively moderated harmful material on its service including material that encouraged the “misuse of controlled medications”. The company noted that it eliminated “millions of pieces of harmful content each day”.

Medical Expert Warnings

“People are injecting materials they cannot confirm. Even if the science behind this drug is valid, these online versions may not contain what they advertise,” said a pharmacy expert, the director of pharmacy at a pharmacy service.

Dr Crystal Wyllie of Asda Online Doctor connected the surge in interest to current price rises for approved weight-loss medications such as Mounjaro. “With prices rising, patients are using social media. But counterfeit injections are highly risky. You can’t be certain what’s inside or whether the environment they were made in was clean,” she said.

Her staff has already seen patients harmed by self-injection from unverified sources. “We understand the disappointment, but purchasing from messaging apps or WhatsApp is gambling with your well-being,” said the doctor. “These materials could be impure or improperly measured.”
