GLP-1 receptor antagonist active ingredients are currently very popular on social media, Swissmedic wrote on Tuesday. Counterfeiters and dubious suppliers are increasingly marketing capsules, drops or food supplements with names such as "GLP-1" as food supplements, capsules or drops. They often bear fictitious seals of approval or logos from regulatory authorities such as Swissmedic.
Products advertised as "natural" contained pharmacologically active substances without any declaration or dosage information. Swissmedic also noticed counterfeits and unauthorized imitation products. For example, weight loss injections with fake labels or substances that are still being researched are on offer. This can be life-threatening in individual cases.
