Peptides have a long history of use, but like any substance, they come with potential risks, especially when dosage is misunderstood. While most people tolerate peptides well, there are cases of confusion regarding reconstitution and dosing, leading to mild side effects. Overdosing can result in reactions such as flushing or itching, but serious health issues are rare. Some peptides, particularly those affecting human growth hormone, are often misused, prompting discussions about safe practices.
