Dr Crystal Wyllie of Asda Online Doctor connected the surge in demand to current price rises for authorized weight-loss medications such as Mounjaro. “With prices increasing, individuals are using online platforms. But counterfeit injections are extremely dangerous. You cannot know what’s inside or whether the conditions they were produced in was sterile,” she explained.
