GLP-1 medicines such as Semaglutide (sold under the brands Wegovy, Ozempic and Rybelsus), Tirzepatide (sold under the brand Mounjaro) and Liraglutide (sold under various brands) are licensed to treat certain medical disorders and should only be used if you are overweight or diabetic. They should not be used as a way to lose weight for aesthetic or cosmetic purposes.
Counterfeit and concentrated powder forms of the medicines have been found on sale and there have been incidences of severe side effects. You should therefore not buy from unregulated sellers, such as beauty salons or on social media.
The only way to make sure that you receive a genuine GLP-1 medicine is to obtain it from a legitimate high street or online pharmacy, with a prescription issued by a healthcare professional.
