Several experts said the popularity for retatrutide could be linked to the rising cost of licensed weight loss treatments such as Mounjaro.

Platform Moderation and Safety Measures

A spokesperson for the messaging service said it regularly monitored dangerous material on its platform including material that promoted the “misuse of controlled medications”. The organization noted that it removed “millions of pieces of harmful content each day”.

Healthcare Expert Warnings

“Individuals are injecting materials they cannot confirm. Even if the science behind retatrutide is valid, these online versions may not contain what they advertise,” said a pharmacy expert, the head of pharmaceutical services at Chemist4U.

Dr Crystal Wyllie of Asda Online Doctor linked the increase in demand to current cost increases for authorized weight-loss drugs such as Mounjaro. “With prices rising, individuals are using social media. But fake treatments are extremely risky. You cannot know what’s inside or whether the conditions they were made in was clean,” she explained.

Her team has previously encountered patients harmed by self-injection from unconfirmed sources. “We understand the frustration, but buying from Telegram or communication platforms is gambling with your health,” stated Wyllie. “These substances could be impure or improperly measured.”

Manufacturer Position
