A representative for the messaging service stated it actively moderated harmful content on its service including material that encouraged the “misuse of controlled medications”. The company added that it removed “millions of pieces of harmful content each day”.

Medical Expert Warnings

“Individuals are administering materials they can’t verify. Even if the research behind retatrutide is sound, these digital products may not include what they advertise,” stated a pharmacy expert, the director of pharmaceutical services at a pharmacy service.

A medical professional of an online medical service linked the increase in demand to current price rises for approved slimming drugs such as Mounjaro. “With costs rising, patients are turning to social media.
