Safety notes

Modern long-term safety data are limited. Product quality, injection complications, metabolic effects and use alongside other weight-loss agents require caution.

  • Not approved as a prescription obesity medicine. Regulatory treatment of compounded or research-labelled supply varies, and it is prohibited in sport.
