be wary of medication from an unknown source
“Slimming medication” advertised as quick working or “smart medicine” that helps users focus or gives them a lift or makes other eye-catching claims could contain narcotics.
Products such as these often use prohibited drugs as ingredients to suppress the appetite or provide a pick me up. In the short term they might provide positive results, but individuals can become addicted without noticing. This is not only bad for your health it is also illegal.
