The idea to question
An injection is just another way to take the same thing.
The short answer
A shot puts medicine directly inside the body. Germs or poisons in the shot can enter with the medicine. Shots bypass some of the body’s usual protections against germs and poisons, according to warnings sent to peptide sellers by the Food and Drug Administration (FDA). Injections can therefore cause serious harm. FDA’s explanation to peptide sellers

Quality is part of the care question
Poor preparation can let germs into a compound or leave it with too little or too much of the working ingredient. FDA describes these quality problems. FDA on preparation quality
Compounding is preparing a medicine from ingredients rather than providing the finished drug-company product. FDA’s compounding answers
- Who prepares this medicine?
- Who explains its label and equipment to me?
- Who can answer questions after it arrives?
Keep unclear instructions for a real conversation
As of September 2026, FDA describes reports of harm possibly related to people injecting the wrong amount of compounded semaglutide. Some reports describe hospital stays. FDA’s weight-care cautions
A report does not prove what caused the harm. Put the exact product in front of you and ask the pharmacist or whoever writes your prescription to explain any unclear instructions. FDA’s weight-care cautions
